Hi there. I’m in the same dilemma. However, LO napped 2-3hrs at a time at 10wo with 1.5-1.75h A time. He then stopped long naps and back to 30-40min naps. I’ve been extending to see what the sweet spot is but we’re now at 2.25h and 55mins is the longest. He’s now 17weeks and looks like still UT 🤷🏻♀️ Perhaps your LO needs more A time as well?
