S.
I just went through all of this and my son is now 4 1/2.
His foot turned in slightly when he was born but because he went to NICU for 2 weeks it was overlooked.
They would check his feet at every Dr appt and every annual exam they saw it turned in and said he outgrow it. At 2 years they started to get alittle concerned and watch it more carefully and at 3 yr and by his 4th bday last Fall they felt it should of corrected. So we went to Podiatrist (foot specialist and also to Scotishrite hsptl (childrens hospital)
They didn't feel he needed correction surgery at this point they don't like to do surgery unless they have too.
However the Foot specilist saw my son and in 5 min knew he had a turned foot and its caused from the foot turning in
during pregnancy. His foot was stuck in my ribs actually.
It is called Metarus Addustus also causing his shin bone to start turning in. He wears a special shoe insert in his shoes to help his foot be more straight. He doesn't even know there there, and his foot isn't perfect but helped him falling by at least 50% less. I hate seeing him fall so much and 50% is better than before.
If you think there a problem see if your Dr will refer you to a foot Podiatrist ( foot specialist) they will know if he will need any help. My best friend daughter had special shoes the 1st 2 years of her life and her feet are so straight now.
Sorry so long but if you think there something wrong than it don't hurt to have it check out by a specialist. I decided I would at least get 2 opinions before I just let it go.
Good luck !!! The Dr said it beter the younger you take them.
