Hi L. what i would do if he pops up in your bed re direct him back into his bed that he is a big boy and needs to sleep in his own big boy bed that he dont need to sleep with momma is all probably just a phase but you cannot let him there cause he will think that he can just sleep with you just keep redirecting him maybe put a night light in his room or something if its contiuous just do a sticker chart with him is all ....does he say hes scared or anything i would try a night light too it helps both my girls sleep with there light on if it were off they would wake up and put it back on lol good luck :)
