Yeah it's different for all kids. Talk to baby's dr and see what he says. Does he get a lot of ear infections? @xoxo512070

Yes kids will do things when they are ready. If your concerned talk to his doctor at his one year check up

my son says mama and dadda. he rarely says hey. he's 14 months old. boys normally have a longer delay in speech than girls do. it's nothing to be concerned with until about 2 and a half from what I understand.
