Could you have him come with you? - with someone to look after him of course! And if you go into labour in the middle of the night they could bring him to the hospy in the morning.

I know its hard, I was so worried about how DD#1 would go when I had DD#2, but when mum brought her in to the hospy to see her new sister she was fine! When it was time for her to leave she just waved to us and left with mum - DH & I were the ones upset! Lol
