Hi Mamssh, my LO is 14 mos old now, but he can't still talk like mama or dada puro murmur like ehh and ahh.. plus hindi rin ssya focus kapag kausap sya or literal na hindi namamansin... pag tinatawag q sya minsan lang lilingon then wala na... madalas mag gusto nya sa TV nalang. medyo worried lang din kase aq... is it normal po ba?
