Lactose intolerance maybe? (Hopefully not)

Hi everyone! Ask ko lang sana if may same experience kayo with your LO na nagsusuka minsan after breastfeeding him/her or while naka-latch sya like 2 beses sa isang araw kasi ganun si lo ko or kaya after nya magdrink ng cherifer tho pinapainom ko naman sya nun after few minutes para di nya masuka yung milk ko. Is it possible na lactose intolerant sya? If yes how tp deal with it po? Huhu hopefully not :(
