B.P.
Sounds like she is having a hard time adjusting to a new home. At this age its hard for children to adjust. They like things the same. 19 months is too young to drop naps. She probably has a hard time napping because she is stressed out. I know its hard but you have to remain calm and collected. Try doing fun things outside while it still not cold yet. Is there a farm nearby? What about a park? You can meet other moms and kids there and set up some play dates in the future. Also, go to garage sales and pick up some new toys for her. Clinginess in my opinion is a sign of anxiety and it will get better!
