The brassica family - cauliflower, broccoli, cabbage and a few others - can cause a bit of trouble. I cut them out between 3 and about 8 weeks, I think? I cut onion and garlic for a little while too, it seemed to help. Chilli was okay though, go figure. Dried fruit and stone fruit (try that one with a Christmas baby!) were no good either.

I also didn't have coffee or chocolate as they made my baby very spewy, but that wore off somewhere between 4 and 5 months.

My SIL also cut out legumes, pulses and beans. As a vego though, there was no way I was doing that! It didn't help her anyway, her baby continued to be fussy at the boob.

I can't think of anything else that would help.

My DD had really mottled skin too, enough to concern the CHN. I don't eat any dairy usually, and the mottled skin went away by itself.

Hope it gets better for your little bunny.
