Hi
My lo is 27 months and he remembers family members names and calls people their name without being prompted. He also remembers if he asks to do something and you say 'we will do it tomorrow', he asks again the next day. He remembers things like if he has fallen and you ask him a few days later where he hurt himself, he will tell you how and where it happened. He uses 'yes' and 'no' in the right context when asked a question and he tells you when he sees a car, bus, van, police car, ambulance, fire engine, train, plane and numerous different animals and what sounds they make. But when it comes to what he has done that day he's not too good, he will tell you he has been with nana/grandma/mummy/daddy and that he has been out, but he cant tell you specific details about his day. As with your lo nessellis, if I asked him if he's had dinner with an alien he would say yes, lol.
I think they must remember things from being very young, but it's only as they are more able to put words together that they fully understand how to tell us what they have done, so although they remember what they have done, they don't know how to say it.
