Well, I did as what was suggested by the e-mail from friend.
For Micah he slept quite well, as he has been sleeping better these days. Only when he woke up in the morning about 8am that he realised he had socks on.
Max...Max. He woke up at 3am, complained about the socks, demanded to go sleep in this swing and also certain song to be played for him. While we were downstairs, Micah called for Mommy and milk. So I went up while grandma saw to Max. This morning grandma said he only went back to bed at 5am.
Max was still coughing in his sleep, so I guess it did not really work for him.
It was nice for Mommy, though. After putting Vicks on their feet, what was left on my hand was "cleaned off" by rubbing on myself. It did have a nice warm feeling. :)
Maybe you can try this Vicks on Feet yourself next time and see if it works for you. Just that it did not for Max.
