Postponing Fullmoon Celebration

After I gave birth to my 6th child, we decided to have a fullmoon celebration since he is our last. Since MIL was not around on the day he turns 1 month old, we decided to postpone till MIL is back with us, that will be when he is already 2 months old. When he turned 2 months old, I am still not fit and I don't think I can cope with the food preparation and clean up so we decided to postpone the celebration till he turns 1 year old. Furthermore, we are on a very tight budget this month because hubby just upgraded his computers which cost more than 10k.
