Sleep Training - Transition to Crib

This is how/where Little Mister prefers to sleep.  As sweet as it is, after six weeks of being a baby-wearing, co-sleeping Momma, I decided it was time to start sleep training, in the sense of getting the boy to sleep in his crib.  My original ambition was to train Little Mister to sleep in his crib for both naps and nighttime, but after the first couple days, I threw out the nap time ambition and have been focusing only on nighttime for right now.  Here is a little snapshot of my progress so far:

Night 1: 3 minute intervals in crib, Momma lost patience after one hour and forty-five minutes and gave into co-sleeping

Night 2: 50 minutes (marked improvement over the first night)

Night 3: 8 hours with one feeding (hooray! feeling like a genius)

Night 4: Wouldn't last a minute before wailing, Momma lost patience after three hours and gave into co-sleeping (feeling like a failure, but determined)

Night 5: 8 hours 30 minutes with one feeding (yay!  regaining confidence)

Night 6: 5 hours 45 minutes with one feeding

Night 7: 8 hours 45 minutes with two feedings (best night yet!)

Night 8: 4 hours 45 minutes

Night 9: 5 hours with one feeding

As you can see it has been a bit of a roller coaster, but I think we are headed in the right direction.  I believe the key to any sleep training is persistence, consistency and determination.  It is exhausting!  At the beginning of each night I definitely am persistent, consistent and determined, but come the middle of the night, you can see my consistency and determination often slip a bit.   It is just "easier" to let him sleep with me and have ready access to his milk.  I often fall asleep while nursing him in the middle of the night and then I am too lazy to get up to move him back to his crib (I am better after the first feeding than the subsequent feedings, but some nights, I am too beat to even get up after the first feeding). I am trying to be much more gentle with myself this time around and not beat myself up over inconsistency, so I am okay with the progress we've made.  A week and a half ago, he wouldn't sleep by himself at all, so I feel like even a few hours is a huge improvement.  Having him start each night in his crib has also helped me maintain my bedtime routine with Henry (which he appreciates...and demands...).  I have been putting Russ to bed first the last three nights and then focusing my attention on Henry.  It has been working out so much better than trying to get Henry to bed first while Russ is super fussy (he has earned his nickname "fussy Russy" (especially in the evenings)).   Work in progress, work in progress...
