Nap Timing Question

[Jenna's Mum]

Hi, my dd is almost 9 months old and for the past 2 weeks or so we've dropped the catnap and it's going well.  But now I'm having a bit of a problem figuring out her second nap.  Here's her schedule:

7:15am wake and 8oz bottle (actually awake since about 6:30am usually but plays happily till mummy gets her at 7am 
9:15 - 11am nap (goes to sleep easily, wakes 45 mins in but puts herself back to sleep)
11:30am 8oz bottle
2 - nap
3:30 8oz bottle
5pm try solids
6pm bath
6:15pm 8oz bottle
6:45-7pm bed

I do try solids around noon and breakfast around 8:30am also, but she's really not that interested in solids at all so I can't really say she's eating them.  Her first nap is great, she's going almost 2 hours, but the second one is so unpredictable.  I tried putting her down around 1:30pm for a while, but she will often roll around for ages and then only get 45 mins at best.  So now I'm trying 2pm but today she's been rolling around for the past 45 mins!  She's happy in her crib, but not sleeping    Also she doesn't always drink the whole 8oz bottle at 6:15pm, usually she gets about 4-6 oz.  She sleeps through the night great, but sometimes I have a little trouble at bedtime because if she gets an awful second nap then she's overtired at bed time.

Do you think I should try her at 2:30pm for this second nap?  Is this too late?  What are typical nap times for a 9 month old, any suggestions?

Thanks!

We're at about 3 hours before the first already because she's generally awake at 6:30am and I don't get her down for that first nap until about 9:15am... so that's 2.75 but sometimes she wakes before 6:30am... it's hard to tell because sometimes she wakes up and I don't because she's just talking quietly to herself, so I don't know when she woke up    She does wake at 45 mins in that first nap but goes right back to sleep so I didn't see that as a problem, but the second nap is tough.  So I should see what time she gets up from her first nap and then go three hours later for the second nap?  That's what we did today but she just rolled around for an hour before finally dropping off to sleep at 3pm.  I'll try that again over the weekend and see how it goes.  Thanks.

Oh I see... I guess that was kind of a question I had in the back of mind about making them tired enough... when they're really little you try so hard to avoid the overtiredness but now that she's 9 months I guess I need to make sure she's tired enough?  Ok so do you think that if I try her at 2:30 or even 3pm, is that too late to start a pm nap?  Is there generally a time they need to be up by so they'll go to bed okay later?  I mean, if she starts taking this second nap at 2:30 or 3pm and sleeps for 1.5 hours and gets up at 4 or 4:30, will she still go to bed at 7pm do you think or will I have to make it later?  I really like the 7pm bedtime because that's one part of her day that works really well right now    Sorry to keep asking questions but I just want to make sure I understand.  I appreciate your patience and help.

On a separate note, I think it's funny how this website is changing before our eyes with new icons, etc.  I guess the webmaster is working on it literally as we type
