How much does your baby weigh

Brandy • 27 and the mom to 2 beautiful girls, Chloe Elizabeth and Mckenna Leeann 💕
Hi I'm a mom to a preemie. She was due 6/6 I had her 4/26. 6 weeks early. She was born at 3lb 6.7 oz and 16 1/4 inches long. She hasn't had her 4 month check up yet she doesn't have it till the 29th but they never tell me what most babies average at this time but i always forget to ask too. I'm not sure how much she weighs now. Last week or the week before I weighed myself then weighed with her and subtracted the difference Bc I don't have a baby scale. It was exactly a 10 lb difference. So I know she's over 10. They tell me she is catching up quickly and eventually they don't think you'll be able to tell she's a preemie. But whenever people see her they tell me still how small she is. Which I know she still is. Just trying to get a comparison. Thanks everyone. 
I know she is still in newborn clothes but she is in size 1 diapers. She can wear some O-3. It's just usually a little big. 
Here she is :) pretty as ever
