As to the tantrums. I don't know if it is good or bad, but what we did with our son was ignore it. I think he only tried it two or three times. He fell to the kitchen floor, screamed, flailed his arms and legs, writhing and screaming. My husband and I stood over him, looked down on him and determined he was okay and in no danger of hurting himself (all the while, my little guy was very aware of us being there) it was kind of comical and my husband said "that's the silliest thing I've seen" and then we told him we would be in the other room when he decided to join us and we walked away. He carried on for a few minutes, then followed us into our room and tried it again. We did the same thing and went into the den. He gave up. I think this only happened once or twice more (long time ago) but we did not have an ongoing tantrum problem. Don't know if this will psychologically scar him for life, but it did put an end to the tantrums. I now have a 2-1/2 year old grand-daughter that tried a tantrum here. I got down on the floor with her and looked her in the eyes and told her that this doesn't work at Grandma's house and I left the room. She stopped and hasn't done it here again. I am no child psychologist, but ignoring the behavior has worked for me 2 out of 2. Good luck!
