  • Congratulations to the family and well done mum!


  • I had an 11lb baby boy vaginally and it nearly ended up with us both dead. Big babies are really a horrible experience.


  • My baby was half that. Congratulations to the new family, all the best.


  • Congratulations on your beautiful new girl.


  • wow so she was too big to push out? much safer to be delivered that way though. always a blessing though


  • Oh my. The thought of the size of this child physically hurts me. My son was just over 4kg at a week early and he was so big. I cannot imagine. I just cannot imagine. This poor woman!


  • even my twins together weren’t this size and I felt huge, that is one big beautiful baby.


  • Wow- mine weren’t even close to that! 7 pound 8 ounces, 8 pound 5 ounces.


  • Congratulations on your beautiful baby girl!


  • Oh my! No one in our family can beat that! Glad mum and bub are doing well!


  • Oh my what a big babies. Well done mummy for carrying that with you during pregnancy !
    Mine were 3 kg and under, my eldest only 880 grams.


  • Yikes! Makes my 4kg bub look like nothing!


  • my goodness that mother is amazing! – I struggled carrying the extra weight of 6pound babies! – congratulations to them :)


  • I saw this and thought wow how amazing are women, I cant imagine how she could carry this size baby. I had one that was 6 pound then one that was 8pound 8 and I found that hard. They will need alot of new bigger clothes for her. Glad she is healthy.


  • My grandfather was born in 1899 and is reported to have been a stone at birth (6.35kg). There is no birth certificate so it can’t be proven …. but his parents registered his middle name as ‘Stone’. :)
