Baby''s arm twisted

My baby is 4,5 months old, and we''ve noticed that when she straightens her arms next to her body (like when she gets excited), her left arm seems to twist inwards - her right arm is stretched normally so the palm of her fist is against her body, but her left arm also stretches but the palm of her fist faces backwards (so her thumb is next to her body, with her hand in a fist). Other than this, she uses her arm and hand normally, and there is no swelling or pain. Could it just be that her arm muscles need to strengthen in that arm, or should we be more concerned? Other than this, she is a happy normal baby.

I am not sure about the problem with your baby's arm without being able to see her. It is possible that she has a weakness of her left arm which is known as an 'Erb's palsy'.This is only a possibility based on your description and it is also possible that she does not have a problem with her left arm at all.It is really necessary for your baby girl to be seen by a paediatrician soon so that a proper diagnosis can be made.
