#AskTheExpert My almost 11month old sits, crawls, stands with support and stands leaving support for 5-10 secs and sometimes takes few steps before falling down. she smiles, babbles, plays, responds to her name, Recognizes few names and people and look at them when we name them and follows some basic instructions.she claps and waves bye bye. she looks at dad when we say papa and few times we have observed, she heard Papa's voice or saw him and suddenly said pa while other times she will just say papa to anybody or sitting alone. worried when kids understand and use words meaningfully.
