maybe for a day or two.. except for immediate family whom they see and hear regularly they do not remember anyone else.. 

Thank you <u>all</u>

yes they remember and miss them. If the absence prolong for some days...they will forget. initially they do.

no they don remember much..but yes mothers shld b arnd otherwise they wil get restless..

don't really know about other person faces.. bt my lo has been recognising me since very young.. around 1 month or so.. I'm not sure if she remembers other ppl faces too n misses them or not.. but she's definitely restless if I'm not around.
