Weened off bottle/bedtime routine

So my little man is almost 14 months old. We just recently ditched the bottle with little pushback. However, this has changed our bedtime routine. We used to have the last bottle, read, and rock and I was able to put him to bed awake but very sleepy. He'd go right down! Now that the bottle is gone, he's so squirmy and distracted during our stories. I try to give him a sippy with milk, but he just takes a few sips and hands it back. Lately, we read about the first 2 pages of 6 books then I try to put him down. He cries every time! I check the monitor for a few minutes and he's in there just hanging out ... standing usually! He eventually will lay down and fall asleep but I was just curious if anyone else has been through something like this?!? I know he's tired too... I've tried pushing back bedtime a little and it doesn't make any difference.
