you can get thin copper tape from OSH and make a box with it worund the stalk. the slime from the slug/snail makes chemical reaction and gives them a small shock. think of it like a shock collar for slugs and snails. they dont like it and will not get too close to your babies. good luckWell, I recently read somewhere that using copper strips an inch below and inch above the soil will generate just enough electricity to keep slugs and snails away from your plant, make sure you inspect daily since snails will use branches, leaves, sticks and etc. to cross the copper strips
I believe this information came from Mogie and if you type slugs or snails in the search box, then look for the thread entitled "wtf will slugs do to my seedling"
