Help please

So my husband was trying to do something nice but messed up.. so he went and washed our daughter’s car seat cover in the wash and dryer.. it was not too but he didn’t see that.. I don’t have the money to replace the car seat.. anyone know what to do? It works but the flame retardant part has holes in it... or where to get a replacement cover? My daughter is due in 2months

It doesn’t have warranty in the first place.. it’s two years old.. the warranty was up after 180days.. just want to know if there’s away to replace it, not get told about the warranty or insurance.. I’m high risk and can’t do the stress.
