We're going to be attending a wedding in early May and I'm having trouble finding cute options for my son.

For your guidance:
He'll be about 14 months old.
The wedding will be at a hotel with gardens outside Birmingham. (UK, not AL- so it won't be too hot!)
The wedding is at 2PM.
The bride and groom met at my husband's and my wedding!

So hit me up with ideas! We don't have all the same stores here, but I'd love some inspiration.
