Dd1 4yo is regularly getting 'bitten' by something in the house. I say bitten but it is actually a small white lump which is itchy no visible 'puncture' mark like you would from a flea bite. Dd2 nor dp or I have anything similar at all. It's not specific to any particular room either.
Initially we thought it may be something in her bath as she also has eczema but then it seemed to happen at other times too. I have hoovered and dusted her bedroom so many times and can't find anything. It's starting to become very frustrating and dd is obviously being irritated by something I need suggestions!
