It is SOOOO hard to get my LO to nap on weekends. She'll always end up finally falling asleep on car rides, so she does eventually get her naps in. But it's a lot easier when it's just me, I can stick her on her swing and she's out. When hubby is home I think she's too excited to spend time with him to sleep.
Does it make a difference who is at your house for how your LO naps?
