If baby sleeps on e mattress on the floor, is he likely to keep getting flu as compared to sleeping on a bed?

Yes. Because all the dirt are there. Unless you make sure it’s clean everyday

hmm. If the floor is dusty and the floor is not cleaned daily.

Yes, since the floor gets dirt and dust more frequently

Yes it is possible when the floor is dusty

It's possible if the floor isn't clean

Yeah...I think that makes sense ...

The floor would always carry more germs than when baby is sleeping in his crib. Crib would be a cleaner and safer place in general
