My 3 year old grandaughter is very clingy to her mum. So much so that she won't let my son do anything for her if she's around. I get that favourtism is normal at this age. She goes to nursery & cries in a heartbroken way at drop off. She is the same when she's dropped off here. After about 10 mins with some distraction she is fine & plays happily all day here & at nursery with her friends. It's not the places she has a problem with but it's the moment of seperation that is the problem. She has always been the same since she was born. I would expect her to cope with drop off after 3 years! I'm worried that she won't grow out of it in time for school, that she'll be the cry baby at the school gate who could get teased for it. Does anyone have any advice please?
