First thing I see are some pretty long A time stretches, and I think that might be contributing to some overtiredness. It looks like (and I hope I'm reading your day right) your lo had a 14 hour day - from 6:30am-8:30pm, and BW usually recommends a 12 hour day and 12 hour night. Some babies can do a 13 hour day, but it's easiest to me to start with the 12/12 and get on a good routine in order to actually see what your lo functions best on. Also looks like there was a 3hr A time right before bed from 5:30-8:30. I'm also seeing a few 2 hour A times during the day followed by at least one short (30min) nap. 30min naps are usually attributed to being overtired. At this age my dd was doing about an hour to an hour 15min of A time before needing a nap. If you breast feed your lo may be hungrier earlier, but of course a 3hr EASY would be what your lo would probably function best on. Because it looks like overtiredness is probably a big issue for you right now, I would start with 1hr of A time, and as he/she gets less overtired start increasing the A time slowly. At this age here is what our routine looked like:
E 7 (or whatever time your lo wakes or whatever time you wake him/her)
A 7-8 (or 8:15 or whenever you see tired signs)
S 8-10
E 10
A 10-11 (again or 11:15 or whenever you see tired signs)
S 11-1
E 1
A 1-2
S 2-4
E 4
A 4-5
S 5-5:45 just a short catnap to make it till bedtime
E 5:45 sort of a cluster feed to tank up the tummy before bedtime
A 5:45-7 bedtime routine here
S 7 for the night
Dream feed around 10 (if you aren't familiar with this post back and I'll give more details) and then cross your fingers till morning. If your lo wakes in the night hungry, then feed and put right back down with as little interaction as possible. Also I see you say there are a lot of gas problems. You may want to check out the breast feeding boards if you bf to see what you could do to help that, or if you bottle feed you may want to check out the colic, gas and reflux boards for suggestions there. I hope all this makes sense and at least helps to figure out what direction you want to go next!!! Good luck and keep me posted on how things are going!!
