It doesn't sound like seizures. Maybe gas trapped in her tummy, is my guess. But it's good you went to the pediatrician! PLEASE let us know what happens.
I took her to her ped and she sent us to the hospital for xrays : ( So by the end of today we shall know whats going on with her... hope for the best
My son has been doing that also.... I talked to my ped and he said the jerking movements aer very normal and the bikeriding motion is very normal my son has been doing this since he was about 2 weeks!! I am sure all is fine but I would call the Ped just to be sure! Good luck!
OMG! How scary!!
Have you called the Dr.? I would probably go to the ER.. That would scare the hel* out of me!
Please keep us posted!
