starting baby on solids. what did you do?

I'm starting my daughter on solids tomorrow when she turns 6 months. I was wondering if I should jump into the 3 feedings per day when she starts or I should start with one or two feedings? When you started feeding your LO for the first time how did you start? And what did you start with? Also I heard your only supposed to offer one food every 3 days to check for allergic reactions??? Her next Drs. Isn't until 2 weeks after she turns 6 months and she wants to eat now! Help please mamas :)
