Most definitely. Cauliflower is terrible for wind and I'm sure broccoli can be too. Try eliminating one thing at a time to see if you can work out what the culprit is.

My close friend can't have dairy or coffee while BF as it causes such bad wind in her kids and exasperates their reflux.

Each child is different so it really is just a case of trial and error to work out what foods and drinks effect your breast milk. Good luck
