Unless you two get along real well in small spaces, the baby will not mind, the dogs will not mind, yes it is very romantic until cooking, diaper change, dogs being dogs can drive her nuts plus the grey water tank backed up in the shower pan and the black tank is full and perfuming the space, but give it a try, ya all will like it or ya all will hate it.
