Talk to Pediatrician on Baby Bad Breath

Hi. Mera baby 1.2 yrs old ka hai or uske 4 uper ke or 4 niche ke teeth agaye hain. Main daily din main ek dafa apni index finger ko achi tarha pani se wash krke uske teeth saaf karti ho brush style main. Lekin subha jab uthta hai wo to uske mou se smell atti hai. Pora din to nahi aati lekin sirf subha jab uthta hai jab aati hai.. kiya yeh normal hai teeth ajane ke baad? Kiya main koibaby toothpaste ya brush use kr sakti hon abhi jabke use abhi spit krna nahi ataa?? Uski diet main soji khichri dalya banana or milk hai abhi to... Phr yehi bad smell kyu??
