I am a SAHM so I'm sure that has a lot to do with it. My 15 mo DD is so clingy, I literally can't get anything done without her wanting to be picked up, she will follow me everywhere and cry at my feet until I pick her up, which I inevitably do for a quiet life.
She will hardly ever play with her toys on her own and would rather sit on my lap and play, I am the centre of everything.
I have two older DSs who are close in age, at one point I had a baby and an 18 mo but I don't remember them being so clingy or intensive. She is very sweet natured but some days I am just praying for bed time, she even cries when she is with DH and I leave the room.
