DS will be 11 months tomorrow. We went on vacation out west the first two weeks of July. Since being back, DS has increased his nighttime wakings from once to getting up every 2-3 hours.

His solids intake has remained the same but the amount of BM I am sending to the sitter each day has decreased by 3oz (I am pumping that much less each day). We have added a second nursing session between when we get home and he goes to bed.

In the past two weeks he has also started crawling on all fours (vs. the combat/drag one leg behind him crawl he was doing), cruising around furniture, and letting go to stand on his own for a few seconds.

Does this sound like a sleep regression or reverse cycling?
