My 5 month old DD has recently started to squeal a LOT. Not crying, this is when she’s happy, she’ll smile and squeal soo loudly lol. She even sometimes wakes at 5am to squeal for an hour before going back to sleep, not waking from hunger as she doesn’t want a bottle when offered. Is this normal, is she just finding her voice? I don’t have any friends whose babies do this and some even have commented why is she shrieking so much! It’s really loud, like as loud as an adult could squeal!
