My daughter has been super clingy and fussy. All she wants is to cuddle and chew on my hand. She's drooled through a shirt and blanket. I don't know if she's starting to teeth or what. I tried looking in her mouth but couldn't really see. I have no idea why she's acting like this. When her dad was home she just wanted to sit on his lap cuddle and chew her hands.
