Hard to say but that wouldn ' t be a bad guess . <| sep |> Before I had my first child I read all the books and thought I knew what to expect . So first son comes along walking at 10 months , running at 11 mo , doesn ' t talk much just basics like mama , kitty , etc . At 24 mo not beforehe ' s saying full sentences and has amazing handeye coordination . At 3 yo he ' s reading , doing math And learning 2 other languages . And then 2 nd son comes along Starts talking at 8 mo . Talks in full sentences at 13 mo . Doesn ' t walk without help until he was 16 mo . Didn ' t begin to run until 18 mo . Learned the keyboard at 22 mo . Started learning 2 other languages at 24 mo . Started reading math at 2 12 yo . BTW I did work with my kids daily . But then I wasn ' t trying to go to school along with working , so I did have the time . What I ' m saying is every child learns and progresses at their own pace . They each succeed in their own areas of interest . The fact that the babies were being compared to each other is so wrong that I don ' t even know how to express it . In addition , the babies aren ' t puppets to put on an act or a play . They ' re babies who have feelings and just want to be loved . You said it best fuck them !
