Do you have a routine for nap time?? Maybe try it a little earlier- before she gets fussy/shows signs of being tired. She could be overly tired & if that's the case they tend to have a harder time falling asleep. If I miss ds2's window (he's 19 months) he'll be up for three hrs past when he needed to go!
& at this time period in your lo's lives the house is always going to be a little on the messy side. You're busy loving babies!
