The short napper πŸ™„πŸ˜΄

We have a little girl who has (aside from literally 3 times) NEVER napped longer than 45mins per nap. She has slept well at night up until this past week (sleep regression!!). We do everything we can... put her down before 1.5hrs awake time has gone by, dark room, white noise, full belly and burped etc etc. I have read they will consolidate nap times as late as 6 months (she's almost 15wks old)... but geeze, it's so hard to get anything done in such short increments! Sigh... any tips?? Anyone dealing with the same?Β 
Just needing to vent after a long night of 45min sleep cycles and just finished a 30min nap πŸ™„
