look up any word, like ratchet:
The action of checking a baby's diaper(s) for wetness, soiling, or proper fit. Feeling the diapers for any wetness or soiling, or by doing a smell check.
After coming inside from doing some gardening, I washed my hands, and went into the baby's room to do a diaper check on the toddler.

I did a diaper check on the babies by gently pulling back the front of their rubbber pants.

My favourite method in which to do a diaper check is by inserting my index finger inside the elastic leg opening of a baby's rubber pants.
