Aap raat mai two times use jaga ke toilet karwa ke phir sulaiye.

Make a proper routine. Stick him to the bed turn off the lights, tell him stories. Keep him active during the day. Daytime nap should not be more than 2 hour. Play With him in evening so that he could jump and get tired which will help him to sleep at night easily. It takes me half an hour to make my baby sleep 😴😂. He also do lots of dramas but I stick him to my lap and narrate a story and makes him sleep.

Mentioned that sleeping time at day time is more,that's the reason...

So first avoid more day time sleep, gradually you can sleep at night...

Hi sleeping pattern differs in every baby and will vary till age of six months after that it will become constant gradually till 1 yr

Try to avoid it and give him cow milk...
While going to sleep,jus give him a glass of warm milk by adding homemade jaggery syrup...or with little honey ....

Hi it's due to colic pain and gases 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

Hi yes but keep on changing position frequently if possible

Have u started semi solids for baby , does baby takes breastfeed?

It's ok.If baby is playful & active feeding , not crying then it's fine .

Normally 4 -6 months main babies tummy neche kr sote h.
But 3 months mai bhi hota h, in some babies. Because every baby is different.
