Kim, I wouldn't worry too much about the day sleep, Liam does about the same in hours (1/1.5 am & 2/2.5pm + 11.5-12 overnight) & he is 9.5mo too. he does 2.5/3/4 in the way of A... to fit so I get both boys napping at the same time
What I would suggest is actually moving to more a toddler feeding. I have edited your Day to mix with what I do & the differing nap times, but as your day is much like my SIL uses for her 9mo & both of us are on #2 & found that it was what we needed to do to fit the older child & to be honest for both of us it works great, esp as often the feeding at night post 6mo is more from low fluid intake than hunger, so the snack time for me is more about getting extra fluids into Liam.
