If you or your SO are Lactose-Intolerant, did your LO have lactose-intolerance too? How & when did you find out if your LO was?

DH is lactose-intolerant, but I am not. One day I had 3 cream pan croissants, and I noticed K had a LOT of poopy diapers. But it was also during the first week, where the poop changes colors and she was already getting rid of a lot of stuff from just being born. But it made me wonder if too much cream intake by me could cause the gassiness and poops?
