can you still do the 4th month anti drool ceremony after missing it on the actual day?

Well no. Cos believe is to be done on 4th mth of Chinese Birth date. Am lucky cos my 1st 2 kids, granny is ard to help and remind me. Thereafter, she passed on and my 2 other kids i will hv to remember not only the date but the things to prepare. Ask ard especially if u have aomeone who is very senior at home.
