Orvis18 on "Every Other Night"

NOt sure how old your LO is but our son (almost 4 mos) is very much like this. The other night he slept 3 hours, then 5, then 3. Last night he slept 4, then was up every 2 hours after that. We also do the same routine at night and try to stick to a 7pm-ish bedtime. I think it has a lot to do with his teething and also how well he naps during the day.
