Nap time?

Is anyone else having a hard time with naps? My baby girl is 7 weeks old and has recently been having a hard time falling asleep during the day unless she is on my chest, being held, or in the wrap carrier. This limits my ability to get things done and throws the "sleep when baby sleeps" advice out the window. I've been able to put her down in the bassinet during the day a couple times but she wakes up after a half hour or so. Wondering if anyone has some advice!
