Wo diya. Mother feed bht kam hai bachy ka pait ni bhrta tha. To feeder dety rhy ab feed bht kam hochuka h. Weight 3 months mn 5.6kg hai. Jb uska weight average hogya tha to meiji fmt py shift hogye. Feed kam hony ki wja sy feeder zyada dena parta. Or 400 gm can 3 din b ni chlta. Or ye formula usy suit krta h lkin bht expensive hai. Lactogen sy uski wo growth na hosky shayad jo is sy h. To kya main isko meiji fmt din main 2 bar deskto hoon? Subha or sham. Or agy pichy apni feed dun or agar pait ni bhrta (jo k har bar ni bhrta) usy lactogen 1 ka feeder de diya krun.
