DS has just turned one - was a massive 10.2lb at birth and in 98th percentile but is now around the 25th, weighing 9.75kg. He looks healthy, eats well and we have fairly skinny genes in the family so I feel like he is ok and has just leveled out to a natural weight but cannot help worrying. Doctors say he looks healthy and not to worry but waiting for his 12 month check in with health visitor. Is this normal, shouls I be worried?!
