White sofa (couch) dumb or not

We are moving soon and I’ve fallen in love with a cream coloured sofa. We have an 8 month old and are planning to have more kids. Are my expectations a bit unrealistic in thinking we can keep it clean? I was thinking of covering it with a blanket for the kids, and they won’t be allowed food near it (I say this now, but I had a lot of things to say before I had my first that didn’t go to plan 🙈)
