4 months baby it's good if the baby has 3naps a day .. maximum wake time for them should be 2 hours..

You need to alter his timing a bit. Don't let him sleep till 11 am, wake him up by 8 am. Let him sleep in the afternoon.. Yes over tired babies will be awake in trh night. When he gets up in the night hope you are not talking and playing with him. And do not switch on the light.. Also are you nursing him to sleep in sleeping position? If not start doing, it will help.

Afternoon m 1 n half hour.... N nyt me 2 baje se subha 11 baje tk...

How many naps does he take in a day... Overtired babies becomes very cranky before sleeping...

I do everything... Kuch farak nhi padta.... N he take burb also.... Din bhae thik hota hai... Jb sone ka time hota hai... Rona start kr deta hai 🤕
