2m old hasn’t pooped

Jacky • 24

So my 2m old the other day didn’t poop for a whole day when she usually does at least 2-3 times a day. she finally did the next morning and it was a big one lol & again she has not pooped for a whole day & a half is this normal? She’s breast feed only and she has gas every now & then but I’m not sure if it’s normal for her to go wihtout pooping
