I'm making a list of things we absolutely need for baby and things we want but may not necessarily need. should a vaporizer be on the want or need list? my s/o says to hold off,he keeps saying wait especially since we just lost baby b (we were gonna name him Joel) but I'm like we still need to prepare for baby a (Julius Jr.) so how long should we wait cause Wednesday I'll be 6 months and time is flying by and winding down
