Red or blue car
Negotiation skills
Train your kids to negotiate when they are playing and every chance, when your kid want something you didn’t want you can offer something else.
I’ve tried this skills with my son 4 years old and feel so happy when he apply this trick with his younger brother with toys or something else.
When his brother has a car he wants to play with he offers him another toy sometimes it works and others not and both can get in tantrums
