We have a rising kindergartener and for the most part, he is a very well behaved kid. He's also a good big brother. However, lately we've been experiencing him acting more like a "baby" in some matters...like throwing toddler-like tantrums, cying so loud that I swear the neighbors can hear and sometimes seriously crying for no reason. We've explained to DS1 that he's the big boy and his brother is the baby. We reward him when he's done extremely well on something and we try to emphasize him starting kindergarten in the fall so he's definitely a big boy. Nothing is getting through to him though. He's even gone back to peeing the bed and he cries when we make him put a pull-up on at night because he says he doesn't want to wear a diaper. I guess I'm just looking for other input to see what other parents are dealing with and if they've dealt with issues similar to this. TIA!
