That is like asking how long is a piece of string. I would say a minimum is 500 baht. For close friends and for people who have worked for me or with me and I want to support, I would give up to 3,000 baht. Some people say that is too much. But, it is really up to you. For funerals I usually give less as these are often for parents or some distant relations of people that I know. For the baby, I have mentioned before that I sometimes give the Buddha image representing the day that the baby was born. However, a practical gift for the baby would probably be more appreciated than say money in an envelope - such as a toy or some clothes. Or, you could buy a Big C voucher and let them buy what they need.
