For anyone who has a baby, just know that all of them cry at weddings, and that's totally OK. Of course, it's always been during a really important moment in the ceremony, or during a really touching part of the best man's speech. It's a baby. Babies cry. Older kids are expected to be kept a bit more in line, but that doesn’t mean it’s easy. Luckily, there are ways to keep them from screaming (or even talking loudly) during the ceremony or more speech-oriented parts of the reception.
