I have a question?
Do babies grow over three inches in a month and five days or did the hospital probably blow the original measurement of 20”?
The shortest measurement from the heels of the feet to the crown of the head was over 23” yesterday.
I do see the baby went from 8 pounds 8 ounces to about three pounds heavier, but I get the feeling they must have made a wrong original measurement.
It can be difficult to measure a baby’s height (length) accurately, so there’s a certain margin of error in the measurements. It wouldn’t surprise me if the measurement at birth were up to an inch too short; they’re very balled up! However, they also grow longer very quickly in the early months. Iirc, an average of 1” per pound of weight gain is not out of the question.
Are you sure it’s the same baby? It could have been switched on you.
Does it make a lot of noise and other messes? Does it seem determined to prevent you from getting a proper night’s sleep?
It’s probably not yours.
