DS has gone into separation anxiety overload in, like, the last two or three weeks (coinciding, as usual, with his becoming more mobile). Its come to a stage where I can't leave the room without him screaming and half the time even in the same room I need to be holding him. Its quite rare for him to be able to play alone these days, something he used to be fairly good at.

Does this sound like normal separation anxiety, or more than usual? I guess my concern is that about 4-5 weeks ago he started FDC, but only one day a week, so its not really a big deal. But I'm afraid that he's got freaked out by it and suddenly really scared- have I broken him??! Or is this just very normal? If so, how long does it last for?
