Playing too hard
A laughing baby is adorable and we all look forward to playing with our child, but we must be gentle because babies are extremely fragile. Shaking them, for example, can lead to permanent neurological damage. The ratio between their arms and body does not allow them to be lifted by the hands either. Playing this way could dislocate his elbow or his shoulder. It is best to tickle him and rock him gently. Big games will come later.
