I don't know very much about reflexes but I think the asymmetric tonic reflex is supposed to disappear by 5-6 months...that's the one where they look to one side and do the Usain Bolt. LO is 6 months and we've been noticing lately that he's definitely doing it still and in photos it's obvious that even sitting up he's constantly doing it, which we never saw before.

Has anyone else's child had this not disappear? Or do you know what it means if it doesn't?
