Did he make another appointment??
One other thought. The doctor is there for you and your child. Next time he/she talks to you and you do not understand,do not be afraid to ask them to explain again. You need to understand and the dr. is not doing their job id you do not. If you do not understand then...well, have him write it down so that you can check later what was meant. You could bring the info here and we can help.
