I've read on here that if you are not inviting children to your wedding you just address the invitation to who you are inviting, which would be just the parents. But I'm still unsure of how it works with one particular situation. By the time of my wedding, my cousin will have a baby who is 11 months or 1 year old. All the situations I've read on here were about children who are 9-15 or so. If children were invited, would a baby that young even be on an invitation? I'm concerned that my cousins will just assume their baby is invited because he will be so young and he's too young to have his name on the envelope.
I know my wedding is still far away, I'm just curious about this so I thought I'd do a little research. I think he will be the only child between both of our families so if he ends up coming it's not the end of the world - I just don't want a crying baby during the ceremony. My cousins will be coming from about 2 hours away so I know they will be spending at least one night here - my cousin's wife (the one I am only related to by marriage) could probably have her mother stay with the baby over night but I don't know if it's unreasonable to expect that they might leave a baby that young over night.
ETA: The child has not been born yet, he is due this spring and my wedding will be just about 1 year later.
