Normally my LO sleeps 11.5 hours at night, and 2 hours after waking, goes down for a nap which can last anywhere from 90 mins to 2.5 hours. We have always struggled with the 2nd nap. I've tried putting her down 3 hours after she wakes from the first, 4 hours, and 5, and neither seem to guarantee me a solid nap. I feel like its always hit and miss. The past few days, she's been waking up from it after 10 mins. I know that many kids drop their 2nd nap close to the 1 year mark, but my LO is only 9.5 months old.
