My youngest DS was 7lbs (full term) at birth and of average length. He quickly shot up and by 6 months was well above the 99th height/weight curves.

He’s now a 6’4, 200lb 13 year old.

I have three girls and all were born in the 40-50th percentile, shot up to 99th by a few months and have come down over the years. The youngest is two and still 77th percentile for height. I’m 5’3 and 100 pounds and my husband is 6’0 and 185. There is no way statistically our children are going to be 99 percentile babies… same with your kid.

I have a big 6 year old now who’s been on right about the same curve as your DS. I just looked at his old stats and it looks like he was also 45 lbs and 45 in at his 4 year appointment. He’s still tracking in the 99th percentile for height two years later, but thinning out very slightly. He’s 57 lbs and 51 inches now, and larger than several kids in his older sibling’s 3rd grade class. I’m curious to see where he winds up too!

He may be big for his age, but 45 pounds is not heavy for 45 inches. My 5yo is about 42/43 inches and 40 pounds and looks quite thin.

My 8 yo is the size of your 5 yo!

lol. Surprising because my 5yo’s size seems pretty average relative to his classmates. Percentile wise he’s only maybe 60th according to our pediatrician? Dh is 5”11 and I’m 5”3. I have tall genes in my family though.

Means absolutely nothing for adult height and weight.

Think of each percentile curve having its own parabolic distribution plot. Many kids stay on the curve and many do not. I have friends who are 6’2” and 6’5”. They are both the shortest in their families. Their child was at the 25th percentile for height as a toddler, then the 75th in elementary and now he’s over 6’ in 8th grade. Both of his parents didn’t get their growth spurts until high school, so he still likely has a way to go.

Same for my sister! She was 10lbs10oz at birth and as an adult she's a whopping 5'0. lol
