Hi dear, don't worry. Har bachcha alag hota h, kuch ko time lagta h. Aap din mein 2 baar maalish kare or exercise karwaye. Usko proper feed karwati rahe. Aap uski growth k liye usko formula milk bhi de sakti h. Mains bhi apne bete ko fm Diya tha. Mere doctor me mujhe Dexolac recommend kia tha. Aap bhi apne doctor ki advice le kar fm shuru kar sakti h

Hey dear,every child is different they grow their own time. you can do massage twice in a day. if you breastfeed eat healthy like paneer, dryfruits and plenty of liquid. add calcium in your diet. like i give formula milk Aptamil Gold stage 1 to my 3.5 months old baby, its enriched with many nutrients which helps to grow baby and provide complete nutrition and helps to improve gut health, digestion and strengthen the immunity. you can try this.
