For my family, eg we have 3 that falls on June (start, mid and end of June) so we will hold the gathering on the mid of June but at the same time not on anyone’s actual day. This is to save cost and time as everyone have work/schools so 3 parties is not very feasible.
Afterall, as long as everyone gets their present, it’s a win- win for everybody 🤣. I would personally hold it on mid Dec. If you feel bad for the belated kid, can hold a small direct family gathering (mom, dad, siblings only) then leave the bigger gatherings on mid Dec 😊.
