You were all right. It has all worked out....at least for 3 nights running and baby(s), I'll take that. Slowly, but surely, both girls started calming down, woke-up less often, just seemed better. Then, 3 nights ago, we quasi-Ferberized them (pretty similar to combo of Laura C and Senja's comments), and instead of going all the way downstairs..I camped-out in the study next to the nursery and started the Ferber routine. It took 3 cycles the first night (ie about 12 mins), one cycle last night (3ish mins) and was zero cycles tonight. Ah, success. And, when they wake-up in the middle of the night, I bound from my bed (yes, the one with my husband...not the mattress on the floor of the nursery!), I fly-up the staircase like a lighting bolt, and calm down before they can take their next breath.
Yep, am feeling pret-tee darn yay and hooray sa-tis-fied (!) right now.....
Shhh.......babies sleeping...!!! :)
