Food suggestion/s please

Hi everyone! 4months preggy mom here...it so happen na may slip disc po ako that might caused me to undergo CS delivery and may worsen my situation. My OB suggested na wag na lalaki si baby sa tummy ko ng morethan 6lbs or 3kilos. Patulong po ako sa foods na hnd nkakapalaki ng bata as you experienced. What food/s and drink/s could you suggest? Appreciate all of your help! #1stimemom #advicepls
