弟弟 is sick...again

弟弟 falls sick quite often after he starts his nursery. Almost every 2-3 weeks he will be sick, mainly due to flu.
This is his first sick since CNY, so is about 15days+ since his last recovery.
This time is out of sudden he caught a flu. Back from school, he kept on sneezing and a lot of mucus came out from his nose. Mommy let him take previous medicine, didn't bring him to see doctor on first 2 days since he has no fever. However, there is no sign of recovery after 4 days and mommy decide to bring him see the doctor on the fifth day.
As usual, doctor checked his nose, ear and mouth. 弟弟 has been so familiar with this and he already known what doctor going to check.
Doctor told mommy must clear his mucus, help 弟弟 to pump out after spray the sea water. Doctor also said medicine doesn't really help much. Lets see if he recover faster is the mucus is out faster.

弟弟 while doing the measurement on weight and height. This is the normal check item on our every visit. Previously he refused to check but now, he stand on the weighing scale by himself : )
