Our LO has to be teething. She's about 4.5 months old, chewing on everything, and fussy. If this isn't teething, I don't know what it is. The doctor has seen her and didn't see any teeth but said it's possible.

That being said, did anyone else's baby sound like a pterodactyl while teething? I think part of it is her testing her voice but it also seems to be her favorite noise to express displeasure before resorting to crying.
