I think my daughter has picked up a bad habit from someone at her daycare. She speaks well (as well as any 3 year old) but she has started doing this thing where she will move her tongue around and it sometimes in the way when she is talking. It's really annoying and it's pissing me off because it just started out of the blue.. I don't know whether to ignore it or to correct her when she does it.

It comes out at random times and doesn't always happen with the same words. It also doesn't happen with words that you would think it may happen (like words with 'th'. That's another reason why it is making me mad, it makes no sense!

Has your lo ever done this? What did you do?
