Hi get it examined by paediatrician, and look for any rashes present in area?

Hi no its not needed?

Tak some fresh aloe Vera gel nd apply on it ... It might be bcz of d heat production in body

Hi give only simple homemade food like khichdi daliya etc And give small feeds frequently and take burp after every small feed

Mostly when baby cry at this age is due to colic pain... No matter how much we try to comfort them they keep crying...
If the baby while feeding is not latched properly then air passes inside the baby to form gas leading to colic pain.. Make her burp after every feed or even between feed.. Give her colicaid drops.. It will quickly ease her colic pain..

Didn't get your question.. Can you frame it again.

Hi take protein rich diet, alsi and take around 5-6 litres water per day and keep the scalp clean and dry as possible

You can go to LEARN option in this app,there is an article,have a look...

Yes it is but only under the supervision of an adult.

if the baby removes the blanket then it is advisable to make him wear socks. Else without socks is also fine. U can buy a sleeping bag for the baby in which he will stay safe and not come out of the blanket.
