My baby is 9kg and uses size 3+ and 4... (I think 9kg are 19lbs to your system...)!

My lo must be a beast. He is in size 4 right now and I feel like I go through so many diapers every month. I don't even know the number. Target has a sale buy three boxes get 20 gift card. I had a 10 off 50 diaper purchase and printed pampera coupons offline and with with a little magic I got 6 boxes for 45 dollars plus one 20 gf that I couldn't use same purchase. Coupons.com has 3.00 off cruisers, baby dry, and 1.55 off swaddler. So you get 7.55 off. If your looking haha. But back to my lo. He weighs prob 20 pounds and size four work great. I just upgraded him. I would go up a size if one box lasts you you a month. I would give a right arm for one box to last a month. Although my lo poops like there's no tomorrow and ebf every 2 hours all day and night still

Lol....Miley is still in size 1's. She just barely hit 13lbs. I'll be buying size 2's next time we get diapers. ?

Aww my baby is tiny 15 lbs as well lol def get a size 3 it'll be a little big but that's ok

I buy 2 boxes of the 24.99 baby dry when target has the buy 2 boxes get a $20 gift card :) if there's any coupons or there's a cartwheel offer, that's a bonus!

We use baby dry too! We pay $37 for the big box of size 3s, I think 204 diapers. And I get them delivered every other month so I don't have to lug both kids out to get their huge boxes of diapers! It's so convenient lol

We use pampers Baby dry! I get 222 diapers for 45 bucks at Buy Buy baby!

That's nice about amazon! I thought about using them but decided to wait and see!

I would move up! What kind do you use? We have a subscription with pampers through Amazon Mom and get our diapers delivered to the door and we save 10 or 15% off the price :)

Definitely move up! Just in case you get to the last half and she needs to up a size.

We switched dd to size 3 at 15lb ^^

We go thru a ton of diapers, I prob change way to frequently, I have always been that way with all my kids! we use about 170 a month!!!

Definitely go up a size! Wow that makes me worry, Aya goes through 1 and a half boxes a month!!

Thanks ladies! ! That's what I was kind of thinking but wasn't sure!!

Yes, she's tiny!! I absolutely love that about her!

Yes I would say move up!!! She's a tiny little one! Lol

I would move up
