My 12 month old ds had been at his cm since October he is fine with the older kids but does nothing but scream when the other baby (10 months) is anywhere near. He reacts as if he's terrified of her. There was a period of a few weeks where he was fine but for the past 5 weeks or so it's started again and doesn't seem to be getting better. When they are out and about at toddler groups he's ok but in the cm house can't tolerate her. The cm is going to give me notice by the end of the month if he's no better. I'm wondering if he would be better at nursery?
