I don't feel comfortable when my baby is with someone other than me or his dad, even family I trust..if he is out of my sight for too long I start to panic a little and he is ok for the most part it's just me, I think because we were seperated a few seconds after he was born and that really got to me..I don't know how to stop being like this but I know I have to get over it especially as he grows and becomes more independent..any advice or opinions on the matter would be appreciated
