My DD is one. She was baby led weaned and had her first citrus when she was about eight months or so, with no ill effects.
About a month ago, I was discussing DD's water intake with a friend (not really enough) and she suggested very diluted fresh orange juice.
I gave it a go - and that night she had a rash. Not like the ones I see when I google "citrus orange rash", not blotchy - a series of red dots, concentrated around her right armpit and down her right hand side. But passing the "glass test" (although I did worry for a minute there)
Since the orange juice was the only thing that was new, I cut it out completely for three weeks. They took a time to go. But by the end of the three weeks, I'd pretty much convinced myself it wasn't the orange. We'd bought some new baby bubble bath as well, and I thought that was more likely.
So last night I tried the dilute orange juice as well - and there it was again. Does anyone have any experience of this? I'm not allergic to anything and neither is DH, so I'm feeling my way a bit here...
