Thank you for your honesty. I have a girl & a boy -he mainly follows her games I'd say. He's coming out of the play alone stage & likes to join DD with her random imaginary games (thanks to Disney cartoons,lol). He's quite clingy to me & more babyish than she was at that age. I've not treated him like the baby of the family so I think it's more his personality. DD can't wait to have a baby in the house but DS isn't so fussed. I didn't have any problems with DD when DS came home as she was only 18 months & very much included. I reckon there may be a few teething problems with DS but as one of my friend's has had a second child recently & another is about to have her second soon, he see's it as normal for babies to appear.
Just a random note...thankfully I avoided the 'how do babies get out of your tummy' question from DD thanks to my sections. She was happy with my answer of 'mummy goes to hospital & the doctor takes it out, see my scar'
