I have twins B/G that are 1 years old but 11 months corrected. My LG has only just started babbling and my LB isn’t he only screams ahhhh I try saying mamma/bababa/dadada he looks at my mouth and holds my mouth while you can see his brain ticking. He holds eye contact and answers too his name. He is very active and so close to walking he’s always here there and everywhere but I’m just so deflated that he has been able to babbling yet.
