Elf - I can't wait to have a bro or sis for my DS so I can see how he interacts with him/her. Must be so lovely to see your kids together and how older DD reacts to lump!
The biggest DD doesn't react to him at all! All her teachers and other mums have seen me wandering around pregnant and now normal size, so *they* have had to stop me in the supermarket to ask what the baby was. She hasn't even bothered to tell anyone at school she has a little brother now!

The best she's done is jiggle him a bit in the bouncy bounce (its a bouncinette, DD#2 has given it a Yo Gabba Gabba style name) when he cries while I'm on the loo, which is nice, but then she runs off the instant I get out ...
