O's naps are getting progressively worse (as if that was possible). It is taking her a LONG time to finally fall asleep. It took me 45 minutes for a 30 minute nap and 1 hr for the next one. I know short naps are common, thats fine (well, not fine, but I have come to accept it), but how long before you basically say f it, its not happening? And if you do scrap the nap, when do you try again? She's 15 weeks old, btw.
