hi my baby boy is three years five months active boy.he normally started speaking meaningful sentences since two years six months. he started asking simple questions most of the time like what is it? but still didn't understand things like why something happened and I am explaining him about everything. but the problem is he is not giving answers about what happened outside?? or what he did the whole day?? he speaks everything else. please suggest at what age babies mostly remember and give answer what happened outside or what they did or ate like that
