Hello Doctor, My baby is 4 months old now. He used to drink 90 ml formula milk every 3 hours. Since two weeks he is unable to drink 90 ml and he is taking only 50 to 60ml every 4 hrs and feeling asleep. Cloud you please suggest why he is not able to drink 90 ml milk like earlier? We are using same Lactogen 1 formula milk. Please advice on formula milk powder as well whether we can continue it or need to change? Thank you.
