last march when i got married since i am the only child my mother insisted that we have a mazinka. my husband was like no why would we? then of course she didnt listen and we did it! we had a blast! remember this YOUR simcha! do whatever YOU want to do! If your child wants it then do it! Again, this is YOUR simcha, not your friends!
Also, I know that Oomis was very mesameach at my wedding and she enjoyed it tremendously!
