I have a 2 1/2 year old. I also have a 10 year old son. The 2-3 year olds are the WORST when it comes to throwing fits! Its a hard age because it really does drain you everyday to deal with it. One thing I was lucky with was potty training. I found potty training charts ( free to print) at ablebaby.com. She was trained before she turned 2!
I don't allow her to kick and scream at nap time. I give her about 10 min to talk to herslf and play in her bed. Then if she has not started to settle down I just go in and tell her its time to go to sleep or you will get a paddle. I do not snack my kids ALL the time But I also do ot let them run the house. The parents are the boss and that is that. Yes teething can cause sleeping problems. You just have to ride it out. I look at my 10 year old when I am having a BAD day and remember how FAST they grow. Then its on to the preteen years!! Let me tell you it goes from one thing like tantrums to being mouthy and wanting to be with friends every second of the day!! Ahhh parenthood!! We all have good days and BAD days when we wonder why it was we wanted kids in the first place!! LOL
