Napping on Tummy

aimalama

I know that it is a huge no-no to let your child sleep on their tummy, but it appears that this is the only way that my DD will nap.  She has digestive issues and I think that napping on her tummy makes her feel better.  She hasn't napped in weeks and then today she has napped 3 times because she was on her stomach.  I'm thankful for the break from crying, but I'm totally stressing out and checking on her every minute.  I've tried to go in a flip her onto her back once she is asleep, but a minute later she was screaming.  Any other suggestions, or do I just let her nap like that?
