How long does a baby's memory last? Parents leave their babies over 6 weeks at IFC all the time for 8 hours a day, but they don't seem to have forgotten mama when she returns. What about if you left a 6 month old with her grandparents for a whole weekend...would she forget then upon your return?

I don't think he will totally forget anything per se. Studies have shown that a baby's recognition memory, that is the ability to identify people and objects he has seen before after a delay or time apart, will increase dramatically during his 1st year. Moreover studies also have shown that at 3 months, babies can remember new pictures or toys shown to them 1 to 6 days previously. Since they've been with you pretty much since birth, your face and presence would have been imprinted on the baby's memory. Don't think they will forget their parents so easily :)

I don't see how will the baby forget. baby has been in your tummy for nine whole months and been living as a part of you. they won't forget you.
