Quoting i made a vagina.:" Find out WHY he's acting out. WHY he isn't behaving. at 4...he can communicate his wants and needs. ... [snip!] ... wants and needs. Has he been getting adequate outside play lately? my kids act up when they're bored & have built up energy."
THIS! i know my DS really really acts up during mid-winter & mid-summer b/c activities outside become a bit more limited... other than that my pedi said you just have to keep doing the correction over & over... hard, i know but it does get better!
