my baby is always on the lower limit of ideal weight. what to do to increase weight? please give some suggestions

A. till completion of six months you can give only breastmilk or if required only formula milk can be given. not to worry. they will gradually start gaining weight. try and feed for longer duration so that baby gets enough of fore milk and hind milk. hind milk is thicker and helps in gaining weight in babies. you eat well and frequently breastfeed .
