New baby sibling book recommendation

[BestBigBrother]

I am looking for a present for a child with autism to help prepare them to become a brother for the first time. I've found a couple online but without seeing the content before buying it's tricky so wondered if anyone had any specific recommendations for books about becoming a sibling or sharing mummy's love..etc?

Mine enjoyed this one www.amazon.co.uk/Im-Big-Brother-Joanna-Cole/dp/0061900656/ref=nodl_

It's simple, gentle and realistic, shows the baby being cuddled, fed, changed and it's all from the bugger sibling's perspective. It also shows both mum and dad involved with the baby, and mum in her dressing gown one morning.

Oh, forgot to say that it's a bit American, eg talks of diapers but we just changed the word. And it shows bottle feeding but I adapted that to non specific feeding without my eldest noticing.

My DS was 2.7 and has ADHD.

He loved "knock knock who's there"

It doesn't go into sharing mummy etc just the arrival of the baby. There's a line at the end that goes "hello little baby, sweet as can be" and for months he called his brother "sweetie"

Thank you so so much!
