I'm not sure what you mean by eating gets messy? It looks like your feeds are all about 3 hours apart, which is probably fine. You should actually probably be moving more towards a 3.5-4 hour EASY, but that will happen as your increase your A time and your naps get longer. It's kind of spooky how this works, but Tracy Hogg is a genius!
As you increase your A time, your LO will naturally sleep closer to 2 hours, which then makes your feeds more like 3.5-4 hours apart. You'll probably end up with 2 long naps and 1 cat nap once you're done stretching everything out. Or, you'll end up with 3 longish naps of 1.5 hours and no cat nap. At any rate, it will resolve itself -- just experiment with stretching, keep your EASY going (in other words, always do it in that order, regardless of clock times), and you'll find the sweet spot in A time where she's comfortable right now!
I'll tell you my secret too: about every 4 weeks your child will be ready to increase A time. i found with my son as soon as naps started shortening again, I'd just increase A time by 15 minutes and voila! Back to long naps! Obviously, when babies are ready for an A time increase varies from kid to kid, but 4 weeks is the avg., so just keep that in mind every month! Also, the amt of A time they're ready to increase varies as well, but 15 minutes is usually a useful guideline, so start there and adjust (forward/back) as necessary.
Make sense? Or clear as mud?
