At 8 months Nitro was 34.2kilos = 75.25 pounds. I keep a record of his weight on my phone, I find it interesting to track his progress. His average monthly weight gain was approx 1.2-1.6kilos = 3.52 pounds. This morning at 16 months he weighed 39kilos = 85.8 pounds. Didn't track my kids' weights, oops.
