I think my 8mo is suffering separation anxiety - he previously slept 12 hours, but now wakes up every night at 1am, then 3am and screams and screams and screams until I pick him up. He gets very hysterical, but don't think he's teething as he doesn't seem in pain and instantly goes quiet when I (only, not DH) pick him up. I'm getting into the habit of rocking him to sleep (unhelpful) or putting him into our bed (ditto), which is not helpful long term. I tried patting his head to sleep but it was taking an hour or so, then he would sleep for 10 mins and the whole thing would begin again. Would be ETERNALLY grateful for any tips - baby no. 1 and clueless!! xxx
