... if I didn't ask for the babysitting?
We have very little support from family due to geography, but we make it work and never ask for help. MIL and FIL have asked to babysit as they love our DS - lovely for all of us, DS aged 2 gets time with GP, we get a few hours to ourselves. Babysitting between 12-5. WIBU to ask them to do no television. We severely limit screen time as DS is a bad sleeper and we find it helps. Also no sugar etc but we leave meals and snacks prepared.
If I requested childcare I wouldn't set rules but in this case AIBU? He has lots of toys and healthy snacks, they don't have to do anything except play with him (DS very spirited!)
