Gained 2 pounds

Yay! Stepped on the scale yesterday and weighed in at 115... stepped on the scale this morning and weighed in at 116!!! Ya know you weigh less in the morning so I'll weigh myself again tonight.  I may have gained more weight than I know. Could  it be that I tried solids again yesterday and pigged out on 3 bowls of rice? I've been eating cream of chicken and mash potatoes for the last month...
