As for the children's birthdays, we could either organize them and celebrate together with them as it would be easier in terms of presents and travel time. The other option is we can have a party for each one of them separately such as one at your place and then I'll have them a few days to celebrate their birthdays with me. I am fine with either one of these options and can be flexible on this one.
