Yes i have my little boy in a brilliant early intervention centre. He's been there since the start of the year and they've been a great help in getting his development moving along. It's also a nice place to go and feel like part of a group, whereas if i'm with my 'normal' mother's group sometimes i feel like a bit of an outsider (even though the mums are all fantastic there too). I guess nothing in life is certain, but oh the worry. My best wishes for your sister and niece, i'm sure they're very grateful to have your support.
