Sorry for the strange thread title! I didn't know how else to describe it!

For the last few days, E has been making a really weird sound while she is playing or eating. It's like she's gasping in shock or excitement but it sounds really strangled, like she's having some sort of seizure or something!! The first time she did it I was terrified - it's so loud!

Did anyone else's LO go through this phase?? It's so strange!
