Talk to Pediatrician on Feeding During Night

Salam. Mera ek sawal hai k mera bacha 6 months ka hai wo raat ko neend main uthta hai to main use breastfeed krti ho or wo sioh jata hai. Yeh uski habit ban gayi hai k roz raat ko ya subha sotey main rohta hai or jese hi wo breastfeed per ata hai to thora sa pee kar sooh jata hai. Main usko raat ko bhi formula milk pila kar sulati ho takey wo aram se sooh jaye. Kya itne bacho ko raat main dhood pilana sahi hai matlab is se unke irregular teeth to nahi ayege na?? Or kis age tak bacho ko raat main dhood dena chahye??
