Help with household and twin toddlers

Location: GENT, België

You'll be helping in the household of a busy working single twin mom.

WORKING ARRANGEMENT

You'll make sure the household is taken care of at all times. You'll be bringing and picking up kids from kindergarden (either with the stroller or by car if you have drivers license and proof that you're driving properly).
You're expected to be around and (pro)active when the kids are at home (cooking, feeding, playing, cleaning, organising,...). Your free times are when the kids are not around: every weekday during working hours, unless kindergarden is closed or kids are sick.
During the weekend you're active as well, unless kids aren't around (as is often the case).

You'll be babysitting, playing and taking care of the kids but likewise the household should be properly taken care of.
During the nights you'll be on duty to wake up when kids are awake (which usually doesn't happen anymore) to either put them back to sleep or call their mom.

LIVING ARRANGEMENT

You'll be living in a great house in a vivid city, with great connections to the rest of the country and Europe.
You will have a spacious room with a sink and you'll share a bathroom with the kids. The kids use this one (or we use that one for the kids because it has a bathtub). The mom has her own bathroom.
