hun.
When they have diarrohea like that it is for a reason.
It is the body's natrual response to get rid of a bug in the gut.

I wouldnt be trying to bung her up thats for sure.

Apply a barrier cream each change and wash your hand thoroughly.

Give small amounts of fluid frequenty.

I would hold off on solids (esp if bub doesnt feel like eating them) as the diarrohea will just continue as there is lot of food in the belly and gut for the bacteria to grow on and the body will continue to flush it out.

FLuids are more more important. Water especially, if you want foods go for dry starchy foods like toast or plain pasta.
