DS is 16 months and has been having separation anxiety really bad for the past 1 month now or so. We co-sleep and in the beginning of the night he's supposed to sleep on the cot mattress in his own room until we all go to sleep. I breastfeed him to sleep and then creep out of the room, but he usually wakes about 20 minutes after and comes to get me from the living room. I then walk him back and lie next to him sometimes with boobie sometimes without (usually with and he doesn't usually breastfeed, just snuggles up next to it - and no, he won't settle without the boobie:(..). This goes on about every 20 minutes or so until I give up and go to the big bed with him, where I sit and work on my laptop until late.. Often DH tries to settle him during the evening, but he will just get to the point where he's complitely hysterical and only I will do. He's always slept poorly in the beginning part of the evening, I suppose because he's used to sleeping with mummy, but before he would only wake up once or twice before we all went to sleep, so I gather it's more to do with separation anxiety right now. Plus he has all the other classic symptoms during the day: clingyness when we go to play groups and panics if I leave the room there or get out of his sight for a few seconds etc.
Anyway, I'm going to start a course next month (studying at home), which will hopefully get me a better job working evenings outside from the home. I'm planning to start applying for such roles in about a year's time. I'm just a bit concerned about DS.. I've heard the worst bout of separation anxiety usually passes by the time they are 18 months. Is this true? I'm aware of the fact that they still will experience bouts of it here and there, but hopefully nothing as intense and I'm hoping by then DH would also do.. I'm planning to breasfeed until 2 and we're planning for DH to start putting DS to bed next spring when he's nearing his second birthday so he would be well used to it by the time I'd start working outside of the home. I just want some opinions as to how realistic I could be with him learning to settle with DH by the time he'll be a bit over 2 and I won't be at home evenings..?
