ok some of your A times are a bit inconstant, for a 10 week old the A time they can generally handle is about an hour 15-20mins, that is after a full sleep though so if she has a short nap (less than 1.5 hours) you want to shorten the next A time. i see you actually increased it after the first nap to nearly 2 hours, only a baby around 4 months old can handle 2 hours A time and thats after a full sleep as well.
So what i suggest you do is try and extend her A time to see if you can get a longer nap (45min naps can be from going to bed undertired), if she still take a short nap then shorten her next A time to about 50mins-1 hour and see how you get along there
how does that sound? if that doesnt work we will look at something else
