OK am going to be totally honest here to get feedback; things my close Mum friends don't have a clue about. This may be long but I really could some help from experienced, confident Mums 
I think I need some real help with my DD just turned 4. Good points are she is mature and extremely well behaved, has gone to pre-school from 2 and is very well behaved and sociable at school. She reads and has a passion for learning new things. Although she is my only (I am unable to have any more children don't really want to go into it) she has half- siblings and sees her friends as much as possible.
Fort he end of this term she has been really ill, one things after another, she is quite delicate and not a big eater so she tends to get quite nasty infections (a couple of hospitalisations) and drops loads of weight. She has had loads of time off school and it has been just me and her dancing around her trying to get her to eat and drink, taking her temp and well worrying myself sick about her.
I feel I am a very serious Mother and find it hard to mess about and play and I feel she has turned into a very serious soul because of it. I also suffer from anxiety and when she is ill I just do anything she asks because I am so worried about her.
To get to the point, I don't know if our relationship is normal. She comes into our bed every night and DH sleeps in the spare room. This has gone on from pretty much birth. She is very possessive of me at night. When she wakes (when not at school) she wants to play on her DS or computer and I set it up for her, then I will often have to take her her breakfast and feed her as if I don't she won't eat. The same with lunch and dinner really. She also still has a bottle of milk
I really haven't told anyone that but it's awful. It's just again because she is so slim that I have wanted to get calories into her any way I can. She has never had a dummy but her bottle she loves. I don't think she totally respects me somehow - she loves me but she likes me to baby her and i don't mind to, I have never been "strict" but she has never been "naughty" iyswim..
There are other things but it will be far too long 
Will she grow out of this behaviour naturally or is it something I need to do - to be stricter with her?
