Aww hun, it does sound as though it could be because of charlie's arrival? He had you all to himself for 4years and now he has had to learn to share you. It must be so hard for theor little brains to comprehend this new person in their life. I'm sure it will settle down it is still such early days

I know it is really hard, but have you tried making one on one time with him, letting your
DH look after charlie an another room or go out for a drive while you play with him? I hope you get to the bottom of it hun, i'm sure you will get there soon
