Today I took AbdulRahman to a friend's house. She has a son younger than AbdulRahman by two months. AbdulRahman is 1 year old. So we thought they can play together.
Now AbdulRahman has a biting problem and I thought he only liked to bite me. Today it turns out it wasn't only me!
My friend has 3 children aged 11, 8 and 10 months. AbdulRahman bit the 8 year old on his cheek and kept pulling the 10 month old's hair. Then he bent down and bit the 10 month old's head!!!
So they asked me where did he learn to bite. Honestly, I have NO IDEA!
In theory all the books say you should calmly and repeatedly tell the child to stop what they are doing and show them the positive behavior.
In practice the child totally ignores you and continues to do what he wants.
Plus I have no idea where he learned to pull hair or bite. I don't bite him and pull his hair and he is the oldest from the children he regularly associates with so they didn't teach him either.
I guess you have to choose the system that works with your child because the theoretical stuff you read from books usually do not work.
I have yet to figure out what method will work with AbdulRahman.
