@ellistonpediatrics: Ever pick up a baby and suddenly their whole body goes stiff and straight? 👶 That movement may look strange, but babies have automatic reflexes and postural responses that can make their backs extend and their legs straighten. And as they grow, they also start anticipating being picked up and using their own muscles to help with the movement. Occasional stiffness can happen, but if your baby seems stiff often, has difficulty moving, or something just doesn’t seem right, bring it up with your pediatrician. . . . . #BabyDevelopment #InfantDevelopment #Pediatrician #NewParents Best NYC pediatrician Tribeca pediatrician UWS pediatrician UES pediatrician Brooklyn pediatrician Flatiron pediatrician (VC: @thisisjustice on TT)
