My 3 yr old is a giant and weighs 3st/19kg but because he's so tall he's bang on for him. Your little one sounds like he's the perfect weight for his height. Kids are just built different but he sounds top notch! If you are concerned though, you can speak to nursery, the GP or the health visitor and they can put your mind at ease. He might even end up having a growth spurt!x
We are also october - 96cm and 13.5 kg. Measured few days ago. We always had low percentile … so i guess shouldn’t worry
I would not worry. Every child is different and it also depends on how tall parents are. We have quite opposite - our October girl is 108cm tall (out of charts when it comes to height) but when it comes to weight she has always been on lower end. What is normal I guess as I and my husband we are both very tall and quite slim. But everyone thinks our girls is 5-6 years old and have higher expectations from her so not always easy for her... The most important is that our little ones are healthy ❤️
My 3 year old is just under 11kg and 84cm. She's always been tiny! I've had a few people comment asking if she was prem or they look shocked when she tells them she's 3. I'm only 5ft and my husband is 5ft 7 so our kids will never be giants. All kids come in different shapes and sizes. He sounds perfect to me!
