Hi there

I think its just part of babies. My son is 10 months and he just wants me around all the time. If he is playing on the flood with his toys, I have to sit next to him. If I get up to go some where he starts screeming and crawling after me saying mama mama. If my DH is with him he is ok for a little while then the notices me gone and starts to cry. He is very shy now as well and climbs all over me. I think most babies do it. As for the sleeping, I cant help there as Callum goes down good and I have always put him down so he is use to it. He also goes down for DH if im out. Good luck:
