My DD is overall a lovely, happy and very bright little girl but I am really starting to struggle with this. She is not even what I'd describe as clingy, she doesn't particularly like cuddles and when we go to groups or soft play she just runs off full of confidence! But at home it's a different story. I can't leave the room for a second - it's a challenge to make a cup of tea or even go to the toilet. She just grabs at me and pulls me back to where she's playing. She doesn't always even want me to play with her, she just wants me to be there. She won't be left with anyone else at all. DH has just got in from work so I've come upstairs to shower (and write this post), but I can hear her screeching for me and it's horrible 
Could this be something I've done wrong? Perhaps she doesn't trust that I'll come back More importantly, what's the best way of managing it? I'm a SAHM and she has just dropped her nap too, so it feels a bit overwhelming at the moment.
