Follow needful safely practices at home. Make sure to give healthy food to the baby so that immunity is high. If you are a feeding mother then continue feeding as it will help the baby to fight with bacteria and germs

Increase immunity of her baby. Give Prebiotics rich food, feed breastmilk, and also you can give Prebiotics and HMO rich FM.

Mother's milk helps in improving immunity. But if the mother isn't able to feed well, you can go with Aptamil gold formula milk. It has HMO and prebiotics. These boost immunity and gut health.

I suggest you give the little one good amount of prebiotics and HMO based diet as that helps in boosting immunity
