This is such a fun and useful book! Not only is it a great place to track milestones, it also contains over 150 age appropriate activities and games to play with your little one. It has checklists for all of the 1st year major milestones, side note with good tips and info for common problems, and each chapter fits with the corresponding month from the 1st month all the way up to 12 months. They each contains highlights and challenges as well as space to write notes about your baby and learning and development each month.
This would be great for an expecting or new mom gift!
There is also a place in the back of the book where you can write letters to your baby, "a day in the life" at 3, 6, 9 and 12 months, and spaces to write about places, books, games and more. I highly recommend.
I did get a copy from Callisto Publisher's Club but the opinions here are my own.
