Hi and welcome to HCM!
Thanks for posting your query here.
Two feet height for a 2 week old baby is too much. At this age the skull bones are not matured and there is lot of elasticity in the bones. Hence chances of internal bleeding
will be there. As it occured two times it is a wise decision to consult a doctor eventhough the baby is active.
Please take care of the baby and keep pillows to the side of her. This will prevent her from falling down.
Hope this helps to you.
