If you are worried about the mik supply, look at baby! Enough poos and pees and meeting milestones, milk is plentiful. If you are still worried, blessed thistle and fen-u-grek togehter will boost supply. Also there is domperidom, a safe prescription drug that Dr. Newman can prescribe that boosts the milk supply.
Cows milk does not equal mothers milk. Be careful about the amount of dairy intake as the milk proteins within the cows milk will be hard on baby's tummy (most of the time) and they will be fussy, gassy and miserable!
