Very troubled over 1 yo birthday party. Wanna diy dessert table but idk how to gauge the quantity per food item to buy. How many pastries should I get? How many pieces per pastries should I get? I will have many many guests but my hub says usually no one eats. ?

Honestly speaking, usually dessert tables are just good for phototaking purposes - which is also kind of why people don't eat the things there, because the table has to look "full" and "extravagant" for phototaking! I didn't have a conventional 1st birthday party (no dessert tables, no family - it was a social lunch for needy families), so I can't recommend or advice on the quantity - but perhaps just use it to put door gifts for your guests (if any)? So it looks full and serves a purpose, and people can just take before they go - meaning it wouldn't be empty and people won't be embarrassed to take them either.
