This is a very sweet, very cute story about a little girl trying to put all her stuffed animals and dolls (her "children", I suppose) to bed so she can sleep too.
It has that nice, repetitive structure children adore - she finds a toy, tells it that it's not time to whatever, it's time to go to bed!, and ends nicely with everybody tucked in and "Good Night".
The illustrations are very well done, in a style that looks more classic than it is.
The one concern you might have (I don't, but you might) is that it's one of those books that doesn't show parents. If you're creeped out by Max and Ruby, you might find this book a little odd too - the girl single-handedly takes on the parental role for herself and her toys.
Of course, if you don't overthink it too much, it's just a sweet, short little book.
