I absolutely hate my son going to his fathers... He's slept so horrible all week!! I'm lucky if he's slept 2 hours by himself. I legit want to cry. Going to his dad's is awful for him in every way. Idk what I'm suppose to do. I feel like we've taken 12 steps backward in the sleep department and it's cause he goes there and they let him take several naps a day, feed him God knows what, and I'm assuming he has to sleep rather shitty for him too. It's super disrespectful for him to do as he pleases and not follow my lead with him because he thinks he doesn't have too. He's just hurting our child. He lives with me and that's just to bad for him. Routine is everything and I wish he would realize what he's doing to our child isn't right but he's never wrong in his eyes. Sorry for the vent I'm just fed up. 😠
