Family Home Evening vs. Sacrament Meeting

Tonight I was left to wonder, "Why can Jasper just sit super still during a rather lengthty FHE, but he isn't EVER still during Sacrament Meeting?"

After three trips out in the hall I on Sunday I couldn't help but mutter, "Why do we even come to Sacrament Meeting?"

I know the answer to that question.  But when I spend my whole time battling Jasper and feeling like I must be the worst parent in the world, it's hard not to mutter.

I think that's called murmuring in the scriptures!

I am 100% open to any reverence ideas.

Thanks!
