Hi Kelsbels. Big I know exactly what this is like. My DD went through exactly the same thing at 10 months. I don't have any sure fire solution but I can tell you what happened with us. At 10 months I decided to night wean (under a bit of pressure from family and friends - you know how it goes "you've got to do it, it's time" blah blah blah). This was a big mistake because I think it coincided with a peak in separation anxiety. DD became impossible during the day. She was extremely clingy and would only sleep for 30 minutes once a day. And she hated going to bed. Then around 12 months she got really sick one week and she basically spent the entire week on my lap feeding and sleeping. And from that time we inadvertently started feeding to sleep again (which I'd sworn I'd never do). But it seemed to actually help. She got over that extreme clinginess and started sleeping for an hour and a half during the day again. Then when she was about 13 months I felt like she was ready to start self-settling again. And we gradually moved in that direction again (which I confess did involve a bit of crying but it was that angry cry and not that hysterical terrified cry). I think when they're going through that really intense separation anxiety the best thing to do is do what ever makes them feel secure and eventually it passes. I hope it passes soon for you!
