So now things are starting to even out a little bit and I have decided to push for a 1.5hr awake time. So far it is helping with the naps, but I'll know more. I decided to do this once I realized that not even a 1 month old sleep 17-18 hours a day! So a 5 month old definitely shouldn't and even if you adjust their age to 3 months then it's too much. For right now we are staying on a 3ish hour routine, but I'm following their lead on the feedings until we get it worked out.
I'm having to push Tyler, because I think he's gotten too used to the routine and thinks that after being up for an hour he needs to go to bed. So quite a bit of fussing off and on for that last 30 minutes, but I know that when their routine changes (visits, Dr appts, etc) that they can stay up 2 hours.
