hi all! newbie poster and twin mom here... my boys are 16w (13w adjusted) and i need some help before i lose my mind! with a 5 & 3 y/o, i'm no stranger to sleep training and have just about read it all (for singletons) and have had great success. this feels like a totally different ballgame and my sleep deprivation has led to anxiety (i'm hearing phantom babies at every sleep attempt) and total cognitive decline (i couldn't do the simple math to make change yesterday) and basically i'm a weepy mess. hows that for an introduction?! the basics: swaddled (with arms down), same room, separate cribs, white noise, can each do at least 6h between feeds at night, breastfed. the issue: they go down easily (drowsy cues clear) but neither make it beyond the 45min sleep cycle for naps, or can STTN without intervention. the carousel: re-paci, re-swaddle, into the swing, next to brother, separate from brother, into vibrating chair, re-paci, release arms, etc. each time they fall back to sleep, but don't STAY sleeping. big difference over here between STTN and simply not EATING thru the night. but what does it matter when no one is getting any decent chunks of sleep?! yes, we've tried modified CIO, complete CIO (after an hour i give up!), comfort/console, yadda yadda. they go down, just don't stay down. questions: what comes first...my nervous breakdown or resolution to the above? are they too young to CIO or expect longer stretches without intervention? i'm desperate...and if i had time and more functioning brain synapses, i would be able to read more of the posts here, or actually finish weissbluth's book for twins. in the meantime, i look to you for wisdom and hope! TIA!
