The only parenting book I bought and liked is 'how to talk so little kids will listen', but it's more applicable at the toddler stage. There's so much information available on the NHS website now, and I found that some books contradicted what the NHS or lullaby trust advised.
It's really tricky to choose a baby book for someone else these days, unless you know their parenting 'style' quite well. There's so many, based on so many different approaches to breastfeeding, baby wearing, co-sleeping, weaning etc. All of the reading I did was from the NHS website, information the midwife gave me and information from the lullaby trust.
I would perhaps get a more 'jokey' one. There's 'Shakespeare's guide to parenting' if she's into reading. If she read the famous five books as a child then there's 'five go parenting'.
My sister bought me 'little miss busy surviving motherhood' for Christmas when when I was pregnant, as I liked the little Miss and mr men books.
If you have quite a jokey relationship with her you could get 'parenting for dummies', I got it DP for Christmas when I was pregnant, but then he needed it
There's so many 'parenting' books these days, it seems like any celebrity can decide they're a parenting expert and write a book.
