saralyn yes one side. now I nurse her n pump at the same time. save time. as for screaming n crying while feeding, my girl used to be like that when she was one month plus. n its always during the last feed. she will scream n cry while nursing. v scary, I fig its wind in her tummy. hence I added rid wind in her ebm n she seems better aft taking it. had went thru few nights before adding rid wind n its like a magic.
