Hi it's due to colic pain, hold baby vertically after every feed and position properly to the breast so as to avoid air ingestion while feeding which is the most imp cause of colic pain and gases and fuzziness

Anything in excess is always bad needless to say. As moms v r worried regarding our baby's activities. 20 min at a time will not create a big issue. He can watch.
Sometimes v also need some rest and 4 that time u can allow him to watch.
Provide him building blogs. Introduce alphabets . Even u can bring a bluetooth speaker and start plarying rhymes on it. He will listen and njoy.

Deal with her with love.. try avoiding all her demands which r not necessary.. make her realise that she is not demanding in a proper manner..

Prepare him mentally for your second baby. He is very small, so needs your love more. He may feel that he looses his mother's love and care gradually ,which may make him to behave stubbornly. Take more care of him a lot.

M trying everything.. usko khelna hota h to BHI sth m rhte hn but day by day m extremely worried for her what I do...even I could not sleep properly..:(

Have you tried taking away his toys or forbidding him from doing what he likes as punishment?

Hi dear sach kahu to lagbhag sabhi parents ko esa lagta he ki unka baccha highper active he mujhe bhi yahi lagta he. Aap uske intrest ke hisab se use kisi activity me busy rakkho jese drawing, dancing, Writing, book reading etc.

Thats great

Hi that's normal, get your baby engaged with you, play more then it will be better

I sing rhymes in front of baby and show him so much love . After that I will promise him what i cook for him like cake or his favorite food
