The age of rolling and crawling

Babies in M size start rolling, sitting and crawling. This is when many families switch from tape to pants, because pants go on even when the baby will not lie still.

M is one of the best-selling sizes, so shops should keep good stock of both M tape and M pants.

How to check the M size fits

  • The waistband sits just below the belly button and you can slide two fingers under it.
  • The leg cuffs are pulled out, not tucked in, and leave no deep red marks.
  • No leaks up the back or at the sides after a normal wear.

Leaks, red marks or tapes that barely reach the front mean it is time to move up a size.

M diaper size: common questions

Is M the same as size 3?

Roughly, yes. Size 3 (about 7 to 13 kg) is close to the Indian M size (6 to 11 kg).

Should I use pants or tape in size M?

Either works. Pants are easier once your baby rolls and crawls; tape gives a snugger fit at night.
