Help quick...advice on suppositories

[KnickKnack]

Ds had a tummy bug. cant keep anything down.
He has been given a suppository to stp the vomiting, and another for temperature.

He has the motillum at about 5pm.
Can he have the paracetamol one now?
Does there have to be a gap between suppositories? Does one need to dissolve or whatever, before putting in the other type?

Have zero experience with this, neither has anyone in family.

I'd give paracetamol now. has been 2 hours and first one will have melted and beeen absorbed by now.
poor DS.

Thanks, thats kinda what I was thinking. He has perked up in the last 5 mins. The constant vomiting has totally drained him.
