Since the summer hols DD1 (6) and DD2 (4) have become very clingy and it is doing my head in. Although the crying at nursery (dd2) has stopped now, they won't let me leave them anywhere - parties, after school clubs, grandparents etc. They both just start crying and clinging to me. I could just leave them and walk away, but particularly at parties, I don't want to have to lumber another adult with dealing with them. I don't understand the reason behind it, apart from having spent 6 weeks with me for 24/7, but they were fine before. It's not like I've ever left them and forgotten to pick them up. Particularly with the parties dd1 just gets on and enjoys it once she knows I am going to stay, but I can't keep staying, not when it's people's houses that I don't really know. Any advice would be greatly appreciated.
