MIL insists on having our child over for alone (i.e. without me and DH) for long extended visits as early as a couple months old (it's a 4 hr flight away). She even said that when she comes over after the baby is born (we're talking a couple weeks old), that the baby can stay with her overnight in the guest unit of our apartment and I can pump so she can feed him/her.
She has this type of arrangement with her other grandchild due to divorce visitation rights, so she thinks these types of long (as in weeks - even months as a toddler) visits are totally normal. I think it's crazy and she got pissed when I told her that I don't think those things will be happening when our child is born. She then made me feel bad for keeping her away from her grandchild and not allowing her to bond.
What's the earliest age and longest time you'd dump off your kid with the inlaws?
