Yesterday, out of nowhere, my 4yo complained that his mouth was tingly. It was obviously bothering him quite a bit. I couldn't see anything. He went to bed and hasn't mentioned it today.
This evening my 6yo is complaining of a tingly mouth. Not sore, tingly. Not good tingly though, she's a bit tearful.
I don't think she is copying her brother, but she might be I suppose.
No spicy food. Nothing unusual to eat.
Any ideas?
