Hello. My baby is 2 months old. She is a formula fed baby. She has around 500-600 mL feed. I feed her every 2 hours or whenever she demands. She has around 60 mL per feed. At night it’s really difficult to wake her up. Even if she wakes up she will not drink willingly. Her birth weight was 2.9 kg and right now she’s 4.2 kg. Tomorrow she’ll be 2 months old. Is it ok if I let her sleep? Or should I wake her up to feed.
