My son started being really tough to put down and not always staying down. He's always been an amazing night time sleeper, so what the Hell?

I decided no more having a bottle at 5:00 and then going down for a nap until 6:30-7:00 (with bath/bedtime starting at 7:00) now he is up no later than 5:00PM with bath/bedtime still at 7:00

I was all prepared for the pick-up-put-down method and didn't need it! All week he finishes his bottle just before 8:00 and sacks out for the night! Back to not waking until 6:00 or later! Hallelujah!

Here's a picture of him napping (supervised when on loose blankets)
