Mommy-2 Mason-0 :-)
So he put up a good fight tonight, but he's out. What worked for both the nap and bedtime was to do as much of our normal routine as possible (he's fighting the rocking/bottle that we usually do because he knows it's time for sleep). I put him down in the crib and he immediately freaked out. I let him cry for about 5 minutes (I could see on the monitor that he was standing and pretty much flipping out). Then I went back up, started the rocking/bottle up again and this time he gave in, took the bottle and fell asleep.
I hope your LO goes down easily for you!!!!
