Newborns get through more diapers than most parents expect, and toddlers through far fewer. Knowing the shape of that curve makes stocking up much easier.
Rough daily numbers
- 0–1 month — 8 to 12 a day. Newborns feed constantly and their bladders are tiny.
- 1–5 months — 7 to 9 a day. Still frequent, but the overnight stretch starts to lengthen.
- 5–12 months — 5 to 7 a day. Solid food changes the pattern; fewer, larger changes.
- 12–24 months — 4 to 6 a day.
- Over 2 years — 3 to 5 a day, until toilet training.
Over a full month that is roughly 300 diapers in the first month, dropping to about 150 by the first birthday.
Which pack size is actually cheaper
Bigger packs are usually better value, but not always — and the only way to know is cost per diaper, not price per pack. Divide the price by the count printed on the front.
It is worth doing that arithmetic once per size, because the count changes as sizes go up. A jumbo pack of Baby Life Size 1 holds 56 diapers; the same jumbo format in Size 6 holds 32. Same pack, very different maths.
Do not stock up too far ahead
The common mistake is buying several months of one size during an offer. Babies grow through sizes unevenly and often faster than expected — especially between Size 2 and Size 4. A month of the current size and a single pack of the next one up is a safer position than three months of either.
Mini packs are useful here: a small pack of the next size lets you test the fit before committing to a jumbo.
