So Melody's schedule only changed slights from her four month schedule.  When she was around 4 1/2 months old, we introduced her to solids.  So now we have two feedings of solids a day.  Our pediatrician recommended one feeding of solids at first, then after about 2 weeks, we added the second feeding.  I will admit, Melody didn't take to solids very well.  So we actually took a break for about 2 weeks, then picked back up at 6 months.  The goal is just to get Melody used to a spoon and eating.  We haven't changed her bottle size either.  I have updated everything we changed below.
