anyone with a 3yr old

Lisa • Mother of three. Had first child when 19. She had a heart defect and other birth defects but is doing great now. Then had cayden two and half years later and finally my baby boy Skylar 2 years later.

i am needing some advice on what to do with my 3 yr old son. he has become more and more reblious. doesnt listen to anything i say, gets into everything and breaks stuff, is biting just all arpund acting out. He knows how to climb and get into the top shelves in the house so try to hide stuff up there doesnt work he knows how to do every baby proof thing on market, plus knows how to undue all the locks in the house. i put him in time out over and over again, and its like minute he gets out he does something to land right back in time out. i use to give him spankings on his butt (no matks or anything) but then he started sitting down anytime i walked by him so stopped the spanking but i just dont know what to do. im 38 weeks pregnant with pelvic pain, so chasing him has become really hard and he isnt acting out just because baby comming he really dont get at all what going on and he does this for other people too...im so lost... help
