Hi doctor, my baby is 2.7 years old.. I can see is is now getting stubborn , how can I take care of this behaviour? for an example is likes to play his cars , toys in water or playing with pressure cooker and if I refuse him to do that then he starts crying ...after sometime he gets normal when I tell him not to do this it's not good but when he wakes up from sleeping he starts crying for the thing for which I scold him or for which I refused him earlier, this happen when he sleeps at day and even in night (at night he wakes up at 2-3 am and start crying for the pressure cooker or for which we scold him in a day )...how should I deal with his behaviour? how can I reduce this? what can be possible reason for this behavior? Is this normal?
