@hariwahyudi Kid was just born in October.
Over the summer my mother and wife did this project where they got all the baby clothes organized. Unpacked from gifts, washed, put away in drawers.
Baby was born.
Because wife was in recovery, I took the lead on all things baby (except feeding) and was SHOCKED when I went to go change clothes that we had NO newborn stuff.
What the hell?
My mother theorized that "you don't know the size of the baby when the baby is born, so we just assumed size 3 months would be fine".
3 months starts at 13 lbs +
Baby ain't gonna be 13 lbs.
So here I am with a newborn at home and no clothes. I'm not kidding.
Same thing with diapers. For some reason, we had no "size 1" diapers. A closet full of boxes stacked to the top, all "size 2" and "size 3"
WHY DO WE HAVE SIZE 3 DIAPERS IN THE DRAWER. THE BABY WONT BE IN SIZE 3 FOR FOREVER. I HAVE A NEWBORN. I NEED DIAPERS...
NOW!
I did a target order for bulk diapers and bought a ton of newborn clothes and with the baby screaming laying down in his crib I emptied all the drawers, threw stuff out into the hallway to go back up in the attic, and re-stocked my drawers with "newborn" and "0-3 months".
I was so pissed.
Am I (the dad) the only one around here that legitimately needs to prepare for baby?
TLDR:
Yes, you will likely need newborn clothes and size 1 diapers.
Now - that being said - yes, baby grew out of that size in about 3 to 4 weeks. 8 weeks old, now, and 3 months clothes feel tight. Time flies, so you might not need NB size for long, but regardless, you'll need it.
I'd say don't buy as much as I did, maybe buy 4 footies and that's all, rotate between them because baby will grow out of size NB soon, so you don't need to buy a whole wardrobe.
