We are all different and so are our children.
Did you notice just a few toddlers to cough late at night or you were doing some kind of a research which had provided you with this type of information?
My sister has two little girls and I haven’t noticed that they cough at all late at night and believe me I am babysitting more often than I would like to.
I remember that they were coughing late at night when they were sick. They had flue for a few days and during the night cough was the worst. Both of them were having trouble with sleeping because of that cough. But when they get better they have stopped coughing.
If you have some additional information about this subject please share with us, maybe someone else has noticed the same thing as you did.
