My dd is about to turn 4 and has turned into an uncooperative, head strong, argumentative, tantrum throwing monster! She used to be good but at the moment argues with EVERYTHING! I can't tell her anything -she knows better! When she doesn't get her own way she starts screaming then gets really angry -she has hit me, hit my washing machine, kicked the door etc. She was NEVER like this. Of course, I give her immediate consequences and lots of counselling at a later, calm time. She says she'll be good but this only lasts until she doesn't get her own way again. Oh, and she is talking like a baby with this silly baby tone. I don't even think I can recognise her normal voice anymore! She has recently dropped her day sleep on most days of the week. She still sleeps 1 -2 days a week. I know she is very tired. However, she can't sleep 4 days a week as she is at preschool and also she won't get tired enough to sleep until about 4pm. At the moment I put her to bed at 6:30 and she sleeps to 6:30. What I really want to know is if this is normal behaviour for a 4 year old or have I done something wrong? How long do they take to adjust to the no sleep routine? If it counts, she has been "diagnosed" as gifted. I have read that these kids can be very difficult at times. Any advice or encouragement gratefully received. Thanks!
