I have adoped a baby boy newly born 20 days back and giving him NAN Pro 1 powder milk in ratio 1spoon in 30 ml water. Frst I give him milk with sirenge or dropper then I start bottle. But from few days he is unable to absorb milk I consult child specialist he say no bottle use spoon or dropper only. Now my baby always remain hungry for milk due to use of dropper he want bottle. What shall I do and can I use bottle or anything else to let him cope with hunger. As he is ok in AZbsorving milk now but not with hunger. My baby is too week also he is just 2.2 kg. please also suggest I shall I do for his proper growth.
