Gosh, is this not all too familiar!!! Kelsey was a notorious 20, then 30 minute napper. I tried it all. Then several mom's (on this site, and other friends) told me to put her down for 1st nap one hour after initial wake up time. Well, I did, and it worked within 2 days. She started taking 2 hour naps. I assume that since she was so rested from the night's sleep so could sleep easier, then so rested from the morning nap, then second nap was better. She will just every now and then cry for less than 10 minutes at the 30 minute mark, but I've learned not to go in there, and she totally goes back to sleep. Sometimes she even sleeps through without waking at all. Now, she's up 1.5 hours or a bit more before 1st nap, but the second she acts tired I put her down no matter how long it's been or else she's overtired and won't be able to resettle herself. I hope I'm not stepping on anyone's toes since this is a bit un-BW, but it honestly helped me, and maybe will work for you. Oh, and if she has both of these good naps, sometimes she won't have an early evening nap and go to bed for the night at 8 with minimal wind-down. Here's our schedule:
8-8:30 wake and eat (6-8 oz and a bit of cereal with fruit)
10-12 nap
12-12:15 wake and eat (same, sometimes add veggie)
2-3:30 or 4 nap
4 wake and eat (same)
6 maybe a 30 minute nap around here, then a bath afterwards
7:30 eat (bottle only)
8-8:30 bed
If we are out in the afternoon, the nap is only 30 minutes still, but if we're home it's long. I hope I don't jinx myself, but she's been doing this for 2 weeks or more.
