I agree 100%. Do whatever you have to do to get your LO caught up. My son is 6mo. and he had a horrible week of naps last week. By Friday he was so OT, I couldn't believe the sight I saw. His eyes were just puffy and red. It was horrible. Saturday I had to catch him up. This is what I had to resort to for his first nap...
9-9:25 Crib
Awake
10-10:30 alseep with me in my bed while DS1 watched a movie
Awake
10:45-11:30 alseep again in my bed with me next to him still
Awake
11:35-12:30 asleep again in my bed...w/ me
Awake- could have slept more but DS1 was getting antsy.
HIs second nap was 2.5 hours in his crib by himself, straight through. THis would have never happened if I didn't have the objective of giving him sleep any way possible. He knows what he has been taught, but it's hard for him to remember since he was sooooo OT. YOur LO is a bit younger, but you shouldn't worry about AP from time to time. If he basically follows the same routine, then a small bump on the road won't be too disruptive.
