Otherwise with Pimsleur I think you just have to memorize четыре ребёнка but пять детей. Sticking with Pimsleur will leave you with a lot of questions of this type.
It is a lot easier learning the language's grammar -- in this case we just have one grammatical rule: after numbers 2-3-4 (and compounds ending in them, such as 22, 33) use the genitive singular of a noun, after 5 and above use the genitive plural.
