I read that if it happens a lot it can be a sign that something is wrong with The cord? And if they last longer then 15 mins it can be bad to. Well my baby has only had hiccups like 4 times my entire pregnancy I am 34 and a half weeks. Now he has has hiccups twice in one day and the first one lasted 10 mins. It just now started and I will see how long it lasts. I get so worried please any input would be nice...
