Did the nw's start before or after you started the solids? She's pretty young to have solids and it's usually better to only give them once a day, in the morning, for a good long while as the digestive changes can wake them up at night!
How long are her naps? I can see she's only having 30 minutes at 9:15, then not napping till 1:30. She's probably quite overtired by then. That may not be helping.
