Is paper a solid?

If it is, then I guess Alice has "started on solids".  Today in addition to her daily breastmilk, she ate:
1.) her older brother's homework and 

2.) a page from a library book (which costed $30 mind you).  It was a really cool wood-working book from the 70's about building forts and playhouses and toys for your kids. 

Paper is considered organic right?

I can't wait to read all the good literature I'll find in her diaper tonight.
