I wouldn't worry about the hiccups too much, our second ferret Emma had
hiccups almost constantly her first 2 weeks with us. I was worried about
her and asked the vet if it was a problem and he assured me it wasn't.
  This was also the ferret I toted to class in a duffel bag every day
because she needed hand-feedings. She was only 4-5 weeks old when we got
her (pet store claimed 9 weeks, but one eye was still closed) and needed
liquid food. The bag would jump if she had the hiccups really bad. I got
some VERY strange looks that semester!
   Is your Baby very young? We always assumed that was Emma's problem. She
grew out of it, and now she snores, but no hiccups.
 
Marya and the gang.
(Emm sends her love to Baby, HIC!)
