Did you notice that your LO had growth spurts according to their adjusted or actual age? DS would be about 12 weeks adjusted and he all of a sudden went from 3oz every 3 hours to 5oz every 3 hours for several days. Now he is back down to 4oz and is sleeping nonstop. Growth spurt??                
                             
        
Re: growth spurts
DD's growth spurts have followed her adjusted age. It sounds like your LO just had one.
