American Toads vomiting up dead skin?

[Misakimon]

I could be wrong but it sounds like they are just shedding their old skin. When they do this they eat their old skin and repeatedly open their mouths and which I guess kinda does look like vomiting. If they are shedding do not try and pull on the skin as it may hurt them

Ok thank you so much, It may be the skin shedding. I won't help them anymore. Is there anything I can do to help them through this process? Or are they ok. Thank you!
