Welcome! I think you'll find lots of good info here and lots of really helpful people.
It's pretty common for trached kids to go back to the hospital pretty quickly after going home the first time. (we bucked the trend with our 2nd, but then, we originally only lasted 5 days out of the NICU before ending up back in the PICU, intubated, and eventually trached, so I think we got our return trip out of the way pre-trach)
