Is there a connection between tongue-tie and allergies and sacral dimples?

[stottiecake]

Someone mentioned it in passing on another thread and I didn't want to hijack - I wondered if anyone here knows?

ds1 - 4yo- had quite a bad tongue-tie and lip tie. He has severe allergies to milk and eggs. ds2 (17mo) had a mild tongue-tie and has a sacral dimple (I hope that's what it's called - a dimple above his anus and a wonky crack) Don't think he has allergies but his poo is always quite runny but he never seems that bothered by it.

Anyone have any thoughts?

Ds2 has a sacral dimple, no allergies (AFAIK) or tongue tie, but he did have IUGR and is still tiny at almost 3yo. No idea if that helps you
