My DD is 4 1/2 months old. She is almost exclusively breast fed apart from the occasional bottle. She is a poor sleeper and for my sanity we co-sleep, which actually I quite enjoy! But she wakes frequently and requires nursing back to sleep. She is not an easy baby but the two of us have lots of fun. My OH is a teacher and I was so looking forward to this summer holiday because I thought it would be a great opportunity for the two of them to bond more and spend some quality time together. However she's become so clingy recently and if anything it's getting worse not better! She watches me if I leave the room and cries inconsolably if she's with my OH. He used to be able to rock her to sleep occasionally but now she just cries. The moment I pick her up she settles down quite quickly so it seems the only problem is that she's not with me (this occurs with other relatives too). My OH is struggling with feelings of resentment toward her and I'm worried he may get PND as he is prone to depression anyway, though not currently on medication. What can I do to help her and him get on better?! Is this just very early separation anxiety?
TIA.
