We're invited to a wedding tomorrow with our 18 month old DS. Am a bit worried about him wanting to rush up and down the aisle during the service (probably shouting "broom broom" very loudly (he's car obsessed at the mo)) and then having a complete meltdown during the reception when he gets too tired, probably while everyone's quiet and listening to the speeches (if we're really lucky). The bride and groom have been lovely and have arranged a room just off from the reception room for kids to sleep in but I'm worried that he won't go to sleep with all the commotion around.
Anyone got any bright sanity saving ideas about how to keep him occupied and then how to convince him it's bed time somewhere new and potentially loud??
