Jaylon was only in "newborn" size long enough to go through 2 packs and the hospital sent us home with one.
The deal they have at Sam's is pretty sweet, but I will caution you on buying in bulk. Babies grow fast. Jaylon is in stage 3 diapers and that deal works for us now, but to buy that many diapers in size 1 and 2 probably wouldn't have worked to well.
We spend about $40-$50 a month now give or take
