content: I bought this book when my twins were 9 months old and I wanted some guidance on daytime napping, and a lot of friends had recommended Healthy Sleep Habits... I didn't mean to buy 'Your fussy Baby', since mine are too old for that- so be careful when you buy this package that you get both books. I had already read a lot of books on sleep training, and while there were some really good tips here, I found 'The Contented Little Baby Book' by Gina Ford more direct. Weissbluth allows for more discretion which I think a mother needs, and overall I think this is a very good book to be read in conjunction with other philosophies, and you can adapt what works for your style and babies. A must-read if your baby doesn't sleep very much and you think it is OK that way- it's not!
