my DH has his 9 yr old son every other weekend and when he is over he lets him stay up super late! i mean it is usually around 11;30, and last night was midnight!! so DH slept in and they didnt have breakfast till noon this morning. even if you offer him breakfast his son wont eat till he can eat with daddy. i am very much against this behavior! i feel that if he is going to let him stay up late 10 MAYBE 10:30 is latest he should be up. i know his son gets tired, but wont tell his father bc he has so much fun playing with him. (last night they watched 2 movies). when i voice my opinion about it DH ends up getting mad bc he is not my son and i am basically telling him how to raise his son. but i KNOW if his sons mother knew how late he went to bed when he is there she would be P!$$ed!! my MIL has spoken to him about it... i have... his other family memners have, we cant get through. his son gets sick easily and i think that when his sleep is thrown off like that it messes with his immunse system. any thoughts or suggestions?? anybody know where i can find some info on the importance of child sleep patterns or something?? or do you have any suggestions os approaching this a different way? because by now i am just a nag when i talk to him about it.
