My twin boys are 10 weeks old. One of them has his legs as the frog legs position. Till what age must I consider this a normal issue? or is it abnormal already? I thought it was normal that I hadn't asked his ped yet.

  • I don't think this is asking for medical advice. While I personally don't tend to love these kinds of questions, this meta question's highest voted answer confirms this kind of question is fine. – Joe Sep 15 '14 at 15:54

    Could you possibly find a picture or describe what frog legs position means to you? Also, were they early, and if so, at what week's gestation were they born? – anongoodnurse Sep 15 '14 at 17:35

    Has a doctor checked them for developmental dysplasia of the hip (DDH) aka 'clicky hip'? nct.org.uk/parenting/hip-dysplasia-babies – A E Nov 10 '14 at 17:20

According to the International Hip Dysplasia Institute, it can take "several months", and Babycenter.com says it can take "6 months" for the legs to straighten out. While I hardly consider those sites as clear experts on this issue (the articles weren't written to specifically address your question), they do seem to indicate that it is normal for a 10 week old baby to not keep his legs straight.

That being said, one cannot rule out the possibility of a medical condition. According to the American Academy of Orthopedic Surgeons, if your baby has developmental dislocation of the hip, it is best for him to be treated early. I'd recommend asking your pediatrician if you are worried.

    I expanded "this"s into the name of the sites - it is better to make it more clear who you're citing than to require readers to hover on the link to find out. – Joe Mar 18 '15 at 20:39
