there's a nice set of two books published by child's play ( american) there aren't any words, just lovely pictures of the mum and toddler going to the scan, decorating the baby's room, mummy resting and daddy getting supper - next book is about changing nappies, giving bottles, playing iwth baby, that sort of thing. Nice b/c there aren't any words and you can just point to the pictures and say words, or tell your own story. Will check what they're called ( I bought thme from amazon)
I am expecting dc2 in 7 weeks and have a 20 month old. The "My New baby" book in the same series as "Waiting for Baby" is good - has a picture of mummy bf rather than bottle so I have explained that the baby has its milk from mummy and ds has his milk in a beaker - am hoping this will avoid stress over wanting a cuddle too etc. I like that there is no text so we can explain it all in our terms and how it works for our ds etc.
ALso got "there's a house" and "waiting for baby" but our ds is not interested in pg books, just the ones with babies in them!!
