Big amd chunky baby

So today i went to the doctor with my son for medicine for an ear infection and while we were there an older couple were talking back and forth with me and playing with my son. My son starts moving around and trying to stand up on everything so they start asking when his second birthday is. How cute he is. How clearly hes saying mamam when i dont pay attention etc etc. His 2nd birthday is over a year away 😂😂 hes only almost 8 months old. Hes in 18-24m shirts, 2t shorts and stands to a bit over the height up to my knee (im 5'6)
