my baby boys weight at birth was 3.4 kg, He is now 4.5 months old and weighs 9 kg. He is formular fed, Has approx 5 bottles in 24 hours. 200ml most feeds sometimes 250ml. This is my first week in introducting farax. Im just concerned that his weight is increasing to quickly. In your opinion, should i be trying to give him less bottles, and trying with to advance to purae veg, just dont know what the best alternative is.
