Dh used to have a chat to Riley everynight before we went to sleep and both the girls especially Erin would chat to him too. DH used to play music to him and he really loves music now- he played all sorts of music. Its funny now with Riley, and I found this with the girls too, because I am a teacher they are all used to the sound of lots of children and are not bothered by it. Riley could be in the playground as a newborn and not bat an eyelid from the noise whereas he has friends who freak at the sound of more than one older child! Also I used to teach next door to a really loud teacher who little kids are scared of and Riley and I were in her room when he was about 4 months old and she was shouting at her Yr6 and R. was smiling!! (we said it was a soothing womb noise to him!)
DH used to chat about his day to the baby and what they would do when bubs was born etc. I was surprised he felt comfortable with it cause he's not very demonstrative but he loved it.
