Breastfeeding food issues

Michelle

My lo is 6 weeks and I'm breastfeeding. So far I've found chicken fish and pate all upset her tummy if I eat them.

I'm slightly worried this means she's going to have food tolerance issues has anyone else had little one be sensitive when breast feeding and fine later on?

Also should I avoid these until I'm not feeding her or maybe try chicken again in a few weeks to try and build up a tolerance?
