In fact, in any case, as parents at that moment, as long as they are natural and generous, there is generally no problem. The most important thing is to relax your emotions happily. If they are a little nervous, it can also be attributed to joy and excitement. Your speech can be arranged like this; First of all, I can express my feelings as a parent at this moment, then thank all the guests and friends present, then some requirements (that is, instructions) for the groom (son-in-law) and the couple, and finally bless the couple and say thank you again and bow.

If necessary, I can also send your early speech (I have been a wedding emcee for nearly eight years) to see if it can make you write more comprehensively.

I wish your daughter's wedding a complete success!
