It does not affect the immunity. However via breastmilk babies do get certain antibodies which formula feed won't get. But please don't worry I have seen lot of grown ups who were on formula since day 1 and are absolutely healthy n fine. Formula is the only best substitute if your breastmilk isn't coming.

Sge slewping well or playong well .. Or going crying

I really don't understand why animal milk is given to infants it is not a good source of food to baby. It creates digestion problem. Cow milk intake Babies tend to constipate badly. I have also personally observed the oldies recommend of animal milk to infants but they really don't understand the difference between there era and our era..we don't even know the milk that we get is organic and pure. I have seen in news cows are also injected secondly the milk bag milk is also added of sweeteners these are specific reasons why doctors refuse to give cow milk and prefer formula or breastfeed. Baby is too small to digest any animal milk at this point of time. Rather I ve later seen babies developing digestive issues gastric issues in later age. Mera bhi breastmilk Nahi Aaya 50th day se mein baby ko formula de rahi hoon. Mere bhi mother in law and mom ne Bola tha ki cow milk chalu karte hein. I strongly refused no animal milk hence continued with formula. Please check with your doctor first. Keep a close eye on his poos. Do talk to doctor see if you can switch to formula.

Hi no you must give breastmilk without gap

Hi you can take till breastfeeding

Hi it's normal during breastfeeding, if the breast are engorged, get it empty to clear excess milk by pump and fees till your breasts are empty at a feed then offer other breast, also latch baby properly to the breast

Hello

No.

Keep breastfeeding until 6 months. After 6 months start semi solid diet. Your baby is too small, exclusively breastfeed

Hello

Reduction in frequency of feeding will help you out.
Other than that be strict about it and replace breastfeeding with other food alternatives of your baby's liking.

Upto six months breastfeeding only recommended for babies....
After that only you can start giving semi-solid foods along with bm or fm...

As of now continue to give bm only.

Your kid needs a burp that's why he is crying. Don't try to force him to feed. Whenever he wants ur bm try to give him. My son is also doing the same. Try to speak with him during feeding, make a smile n eye contact with him these will help to reduce ur kid from screaming 🙂🙂
