Our opening gambit: "ramp up" daycare plan; a few days/week gearing up to full-time...not in the place she'll ultimately go in the fall, but somewhere easy, casual, to get her used to being cared for outside the house. Seems reasonable, no? (FYI: no.)
Her counter: heart-rending crying.
Our next move: let's try three half-days per week instead of two.
Her brilliant plan: crying till she pukes.
And thus: checkmate. Our king falls. Crying puker reigns victorious.
We decided to call it quits for the summer and try again in the fall, at the full-time center my work offers. It just wasn't getting significantly better...she'd have OK-ish periods for portions of days here and there, but for the most part she simply hated it, for 4 weeks in a row. And what's the best-case scenario at this point...she'd come to love that daycare and it's staff, only to be taken from it in two months to go to the permanent -- and way better -- place in September?
One thing that made it harder for me is, of course, the adoption angle. If we'd raised her since she was a newborn, I might have been more inclined to stick it out. But there's so much we just don't know about her little psyche...was she just being a typical almost-2 year old with separation anxiety? Or was this abandonment issues rising from a much deeper place? We don't know, and decided it's not time to find out. So a few more months with our fabulous new nanny, and then we'll try again. In the fall, I'm hopeful that it'll be better -- at the least, it should be a faster adjustment period, since she'll be going 5 days instead of partial weeks, right? And it's a much more structured place; an activity planned almost every moment (art, singing, walks, snack, etc. etc.). And the nanny will be allowed to accompany her to the first week or so, which should help.
I know the fall will suck too. But I hope, less than June did.
