I don't know how helpful I will be as I have a LSN baby whereas yours seems to have high sleep needs but I'll give it a go. IMO, it would help to increase her A times. 2 & 3 hours are more appropriate for a younger baby. At 9 months, we were already doing 5 hours. Perhaps pushing the first nap to 3 hours also would be the first step. Basically it feels to me that her first nap is simply too early in the day. It definitely needs to be pushed out. And lastly, in order to keep a good sized gap to bed(not too long as she seems to prefer a short A to bed), you might need to cap one of the naps in order to fit them into the day. In a sense, you would be moving towards either a short am - long pm routine or vice versa. How does that sound?
