Its fine for baby to have lunch, its their party! I would do presents, a few sandwiches while baby has lunch, then tea and cake 🥰
We did 3-6 as we had the morning as a family. Baby had dinner/ food along with everyone else and worked well as he’d already had his second nap so was in a good mood and it tired him out for bed! x
We did 2-6 with family and close friends ☺️
We did ours 1030-1230 and little ones had party food with he adults around 1130ish :) worked quite well. Then went down for nap at around 1 or just after
