In the middle of an ongoing negotiation with DH re childcare. PFB so we don't know what we're doing 
How will a toddler (15 months +) be affected by sleeping at grandparents', once a week?
Hypothetical situation: Monday daytime with DM (and DF when he's back from work around 6pm), overnight at GPs, Tuesday dropped back at home in the afternoon, and DM/MIL stay until we get home from work. So toddler would see a parent on Monday morning, and Tuesday evening/night. Nursery Weds-Fri.
We don't see eye-to-eye, and neither do parents/in-laws. AIBU to ask for your views? Not posting mine yet as don't want to sway the responses!
