Yes, something is wrong.
This is not normal.
The child, will suffer and be perhaps permanently delayed, if she is not seen by a Doctor.
"Guessing" at what is wrong, will not help, at all.
What good is guessing, unless something is done about it?
The parent, does not do anything about it.
Is the child eating/feeding normally?
Or is the child, not getting enough intake?
If not, nutrient 'starvation' can also cause, delays in a child. If the child does not feed/eat and is NOT given adequate intake.... then these delays, can become permanent, as well.
This is really alarming.
The child is not doing, what a normal child that age, should be doing.
And she is only 12 pounds.
Which to me means, the child is NOT being taken for regular well-baby check ups. Otherwise, the Pediatrician would have commented on the child.
Yes, someone should say something about it to the parent.
The child, is suffering.
A child, this age cannot fend for herself nor take care of herself.
The parent needs to be, doing that.
Responsibly.
The child is being neglected.
Call CPS... even anonymously.
The child, is at 12 pounds and 1 year old... in the "failure to thrive" levels. And her development/delays, are not normal.
