Holy cow guys! Lol zains still in nb .. I guess I should see how the size 1 fits! He was 8lb 8oz when he was born and is 3 weeks old now. I shall see! Thanks ladies! :-)

Lol mine was in size 1 the day he was born! 10lbs 3oz! But my first was in nb size for a few weeks. He was 8lbs

We started using them yesterday! He is 18 days today and every single time he peed and pooped through the newborn diapers. Now we don't have a single accident! Yay!

My son is still in newborns and he's 3 weeks old and 7 lbs 15 oz. The size 1 diapers are massive on him and we have to fold them down if he wears them. They put him in 1's at the hospital and he was only 7 lbs even when born!

Around a week old. I found the newborns were not very good at keeping things in and several messes were made...so we switched to size 1's.

3 weeks old he was 7lb 2oz at birth but he's a little chunks now I get to see how much he's gained today

My LO went right into size 1 at birth. He weighed 9lbs 7oz when born and is over 11lbs now at 4 weeks old :)

8 days- my lo gained a pound in a week!

My baby been size 1 & he's 2 weeks lol he weight 8 pounds at birth

Mine didn't fit probably about 15 days.

My LO was in size 1 at birth! He was 9 lbs 8 oz. The newborns just barely fit so the nurses at the hospital had to go find him size 1's.

My LO is 18 days old today and we used up the last newborn diaper yesterday. She was 7lbs13oz at birth.

Born at 9lbs14oz and went straight to size 1. nB were way too small.

My baby is 9 lbs and newborn fits big on her. She has a tiny waist and booty lol.

We were in size one at a week. She's growing fast though... Was 10lbs at her 2 week appt

My daughter has been in size 1 since 2 weeks old. She started to have lots of blow out accidents with the newborn diapers.

6 weeks old and still in new born

Logan was born 8 lbs 9 oz and we could do either since birth. At ten days old we had to switch to size one though because he had two straight days of blow outs in newborns.

My hospital uses size 1 so from the time she was born. She was 8lb 3.5oz. We had newborn at home so when we came home she was in them for about 2 days and I didn't like way they fit so we went back to size 1 and she's 13 days old

Mine was in size 1 at the hospital since that is what they gave us. She was in newborn for her first three weeks after that. I just now started using size 1 again since the newborn looked like it was starting to cut in to the tops of her legs too much. On another note, I used pampers since that is what the hospital provided. I opened a box of huggies newborn a few days ago and they did not hold a thing compared to pampers. She'd wet right through them and soak her jammies even though I was changing her often. Dislike huggies so much.

Who my baby will be two weeks tmrw and he's been using size 1 since he was a week old. He's 8lbs 8 oz

When my daughter was 3 weeks

she's two weeks old and we just went into newborn. premie fits better but she pees too much for them especially at night.

Just changed my son to size 1 last night. He is one week old. The newborns were starting to leave imprints on his thighs...lol. he was 7lbs 14oz at birth but at first doctors appointment which was 4 days after he was born he was already 8lbs 2oz!!

After one week. And based on how quick my little man is growing he may be going into size 2 pretty soon.

At birth! My LO was 10.4 when she was born, the NB size was too small :(

Ella was in size 1 at a week old! She was 8.4 pounds at birth and about 9 when she switched to 1s. Newborns were leaking!

My baby is almost 3 weeks and we are transitioning into size 1 (only use at night) because she is soaking through her newborns

Ya I opened the size 1 just to see how big they were and they look gigantic compared to nb lol

My LO is 6 weeks today and still in newborn.
