3 month old changing feeding schedule?

My DD who is 3 months old this week. For the past week or so I have been having to wake her for her last nightime feeding. Her schedule has been 5am, 9am, 1pm, 5pm and then 9pm. First four feedings she's been getting 5oz. The last feeding she drinks 6 oz. So last night, I fell asleep while putting my older son to sleep and she was asleep already and she didn't wake up all night - so she had her bottle at 5 pm and her next one at 5am. That seems a bit of a long time for no bottle.
So my question is, should I just not wake her up for her 9pm bottle or should I keep waking her up for it? Today I gave her 6oz in her two morning bottles to make up for not having her bottle.

We will probably start cereal towards mid-late July. She's also been "playing" a lot more and has been awake more during the day.

TIA

This is what I did:

DS takes 6 feedings of 5oz each one:
9am
12pm
3pm
6pm
9pm (normally awake after nap)
12am (I feed him sleeping)

This schedule has worked wonders for us and if we deviate it will be by an hour earlier all depending on the morning bottle.

I would not wake for a feeding at that point. My DR said at that point if they are sleeping through the night without and still gaining weight don't worry about it an let them sleep
