DS is 14 months. Relevant details: still a fairly poor sleeper and still breastfed. I have never left him much - DH and I have left him with his Dad about twice, my Mum once and a hotel babysitter on our honeymoon. All for less than two hours. However, I have gone out a fair few times (probably less than ten) and left him with DH for an evening, and every time there is some kind of drama. He doesn't settle as well for DH (lack of boob) but he does take a bottle and go to sleep. It's just he's then not as easy to settle if he does wake again, and every time I go out DH has a terrible evening of screaming child. He gets very stressed by the not sleeping as well so I think they wind each other up. Basically I just feel guilty every time I go out. But AIBU to think that he should just deal with it? And also do so without whinging and ruining my night? I'd be home like a shot if there was an actual problem, but unsettled and.clingy child is just one of those things? It's probably only once every 8 weeks or so. And I deal with the baby on my own every evening he's at work (shifts) - but he seems to think because I have the magic boob it's no work at all as I can just nurse him back to sleep. Which is apart from anything else increasingly no longer the case as he's getting less and less interested in nursing. Anyway I'm currently on a train back from London after an evening out with friends, and when he'd asked me earlier when I'd be back I said 'certaibly not before 10.30, probably latter's. When he discovered I wouldn't actually be back til after midnight (earlier train cancelled) he yelled that I was irresponsible (I have work tomorrow -he doesn't) and that it's not fair as he will have to deal with a stressed, poorly slept baby all day tomorrow who will just want me. 
Further info: he now looks after him on Mondays since I've returned to work,and they deem to be fine during the day. It's just evenings that are an issue.
