Any parents have experience of this? My 13mo has gone back to having mustardy nappies again just this last week (normally brown), like the BF nappies of old but not runny. She is still BF but eating solids normally. Frequency has been normal so I don't think it's passing through too quickly. She's started nursery v recently and they suggested teething - she does have a tooth about to cut through but this didn't happen with the other teeth. I wondered if it could be a bug but she seems well otherwise. Would really appreciate any insight on whether this sounds normal or needs a GP call? FTM and learning everything on the go 😅
