My baby is so colicky on his first month, so we kept him in prone position to avoid a gassy tummy. But what really helps was when our doctor advised us to change his milk since he suffer from lacto entolerance, he then now drinks soya milk "isomil". I let him breastfeed but my milk supply seems not enough for him so I mixed it with formula milk. If only he's purely breastfeed I would have nothing to worry.
