My little girl is going to be 12 weeks old on WED and for the past two weeks she is scared of everything. I have a four year old boy who likes to move around and we'll be a kid anytime he talks after it being quiet for a little she gets this frightened look on her face and starts screaming, same happens when there is any loud noise anywhere, or if she sneezes when she is falling asleep, if a door closes, etc... I don't know if this is a faze or what but I get anxiety when my four year old starts playing in fear that she is going to start screaming, and it takes so long to calm her down. My back and body are just exhausted from carrying her nonstop. Has anyone dealt with this? Please tell me this is something they grow out of...
