K.B.
I'll be curious to read what everyone else says because I haven't figured out these 4 year olds yet! (Mine just turned 4). We had a similar situation when my son was 2-1/2. Lots of life changes (newer sibling, daddy on extended vacation, daycare schedule wacky). And he turned into a MONSTER. I couldn't believe it. So after trying all the obvious things and he was so blatantly rebellious in my face. I realized I was NOT having fun and like you I was home with him- a precious thing! So....I decided to change things around and it WORKED! I showered him with love. I didn't punish, didn't scream, didn't time -out (most of the time.) When he got upset about a game, my first instinct was tograb him up in my arms, snuggle him and talk about it. Or, I would distract with a book like you do a one year old. I told him a thousand times a day how sweet my boy was, how much I love him and how he was being a trooper to go through so much. And guess what! IT worked, he settled back down from the "monster Logan" into the normal one and I was able to get into a new routine with my sweet boy back. Best of luck!
