My daughter is will be 1 month on the 28th (this is our first baby) for a good portion of the day her arms and legs will randomly start to flail around and she is not able to control them. When this happens it scares her and because she is not able to stop this from happening she will then begin to cry and she won’t stop until her arms calm down. I have been told it’s normal thing for them to do but I feel so bad that I am not able to help.

Is there anything I can do to help with this? I have tried the swaddles and they seem to help but I was not sure if I should keep her in them all day?

Thanks in advance for any help.
