The book dd has is called "What's inside mummy's tummy'. It has a month a page & has al sorts of lovely details, like how big the baby [comparing it to everyday objects] & real size pictures of what the baby looks like!
We made dd [5 now, but was 4 when baby due] a baby journal.
Just a note pad that she could draw in, put stuff in [she has a copy of the scan pic, a pic of my belly, a copy of a poem I found when she was a baby etc]. She would tell us how we are feeling & we would write it down in the journal for her.
She used to sing to the baby [thru my mouth as she was convinced this was the only way baby could hear]. I let her rub cream on my tummy.
We have had no problems. She loves her little sister & helps out lots [although we don't pressure her to] and the only adverse behaviour we got was a mini tantrum at bedtime for a few weeks, as she hated that dd2 was still 'up' when she went to bed. So If dd2 is not asleep, we out her in her bassinet while we do bedtime.
I made sure we still had special time with her. Dh watches a fave programme of hers, or plays footie in the garden. I bake, take her to lunch now & then, paint/draw etc.
I am feeding dd2, so we use that time to read, as she turns the pages of the book while I read it to her.
Dd2 brought dd1 a special gift in the hospital & dd1 brought dd2 a teddy & a toy dog [which she is 'looking after' for her. She helped us choose clothes etc.
