Wow, I really originally gave this book 3 stars? I must've been feeling generous. Or actually having a baby and trying to find some answers in The Montessori Baby made all the difference. Right now I'm hesitating between 1 and 2, but f i n e, let it be 2. I can't say I 'didn't like it', after all. It's just that this book is perfectly useless. There's really close to nothing in it that'll help you during your first 12 months with your child. Lots of obvious stuff. Some advice which I found dumb from the start so I decided to ignore it. Some advice which I tried to follow and now wish I hadn't (the whole 'don't you dare to swaddle your newborn baby' is quite high on my list of regrets). And besides all the problematic points I mentioned in my original review: when it comes to time-frames, this book keeps contradicting itself so often that it's almost funny. Take any random developmental milestone or an activity suggestion and check when the book suggests introducting it / says it should happen. Check in the text itself. Check in the pretty graphics. Check in the lists at the end of the book. I'll be surprised if you don't come back with 3 different answers. For example: knobbed puzzles! The text says: 9 to 12 months. The chart at the end: 12+ months. The graph with 'movement activities' (p. 160-161): 6 to 9 months. And The Montessori Toddler, which I also happen to own: from around 18 months (p. 51). Well, thank you for clarifying, that's helped me a lot... Honestly, did this book even have an editor?
...wait a second, I really don't see any mention of an editor. The toddler version has 'editing assistance', but this one hasn't.
Ouch.
That explains a lot.
***
To put it in a very un-Montessori way, this book is an uglier and less talented sibling to The Montessori Toddler.
It's hard to write any coherent review of this book, because the level of different chapters varies a lot - with the first half being way weaker than the second. My main complaints are related to the chapter about setting the baby room, more specifically the sleeping area. Just let me sum it up for you. The baby should sleep, from the start, on a floor bed, surrounded by a safe yes-space designed extra with the baby in mind - so basically, its own room, because playpens and such are forbidden. But actually it should sleep in the same room as its parents. But actually, SIDS guidelines say the baby should co-sleep with the parents at least for the first 6 months, ideally 12. But you should start using the floor bed latest when the baby starts to crawl, so around 9 months. Maybe you can use two sleeping areas, one for the nighttime and another for daytime naps. But actually no, consistency is vital, the baby needs one sleeping area to not get confused. Oh, and don't forget, it's all totally possible to do while on a tight budget. Not like you apparently need a huge, childproof bedroom with a dedicated baby area or two high-quality baby mattresses.
Let's face it: it's all a hot mess. I have two theories on what happened in here. Either the authors first wrote about how awesome floor beds are and only just before the book was about to be published they realised that whooops, those ideas go against the official anti-SIDS guidelines (that could explain why the publication date had to be postponed a couple of times...) - or they have different opinions on the topic and were trying hard to somehow combine them into something coherent. If so, then I'm afraid they failed. The whole sleeping topic gets touched upon again way later (I think in 'Putting it into practice'?) and in a clearer way, but to reach this point, you have to first fight your way through the first half of the book - and somehow that wasn't an easy task for me.
Apart from this, the book (again, especially the first half) feels unnecessarily long and repetitive. You know how back at school or uni you sometimes had to write an essay of a certain length, and if you already wrote everything you had to say on the matter, you had to fight hard to somehow reach the word limit? I guess it happened at least once to everyone? Well, that's how half of The Montessori Baby reads. As if the publisher gave the authors a word limit and they had to write the same stuff over and over again to somehow make it. I think the book could easily be some 50 pages shorter - maybe even going on 100, who knows. I don't mind some repetitions and digressions, but this was too much even for me.
And then there are some unusual pieces of advice thrown here and there. For example, the authors write multiple times that while pregnant, you should make connection with your baby by massaging your belly. Not rubbing, touching, caressing - nope, massaging is the word they use. I wonder what medical professionals would say to it - inducing cramps anyone? But my absolute favourite, which startled me so much that I had to reread the sentence a couple of times, is related to spending some quality time with your partner (again, still while being pregnant). The authors recommend that you make it a daily ritual - and that you wind up together by, let's say, drinking a glass of wine. I mean... Excuse me? Is drinking during pregnancy ok now? Are we back to 'oh, just one glass won't hurt'? How am I supposed to take the rest of the book seriously after this?
Welp. So that's the first half. The half which almost made me give up halfway through (but I'm stubborn and hate leaving books unfinished, so of course I didn't).
Luckily, the second half is back to the level of The Montessori Toddler. Lots of practical advice, information, little unnecessary chatting. I loved the chapter on activities - probably because my main baby-related concern was 'what the heck am I even supposed to do with it?'. I can't express how glad I am that the book gave me such a thorough answer to this question (and that apparently I don't even have to actively do that much!). I loved the compassionate, understanding tone of this book, its unwillingness to present only that one style of parenting as 'the right one'. Basically, while the first half left me feeling very uneasy and confused (very much not the effect I was looking for!), the second - just like The Montessori Toddler - made me feel that I grasped it all, I've got it, the fog has cleared up.
And so, after all, I'm glad I bought this book. I'm sure I'll revisit some of the chapters many times in the next months - just as I'm sure that I won't read others ever again. But whatever.
If I might make just one more whiny remark... It'd be nice if the resources page mentioned in the book actually existed. It looks like it's in the making, but come on - the book is already out, you send your readers to that website, so shouldn't you have prepared it first?
