How did you handle cloth diapers and your registry?

Hey ladies, I am 28 weeks with our first baby. I am fully dedicated to cloth diapering him when he arrives- to avoid nasty chemicals but mostly to eliminate the huge reoccurring cost of disposables. I will be a SAHM and I am confident in the hours and hours of research I have done that I will be able to keep up with the laundry routines and find combinations that will make cloth work for us long term. The problem is that none of our families are supportive of this decision- every single person has at the very least said they don't think I will do keep up with it, asked why I want to make having a baby so hard, or straight up told us "he'll be in pampers in a week". Our budget is very tight and we are really hoping that we will receive several of the cloth diapering items we need from our registry at my showers. But with the lack of support, I am worried that no one will want to purchase anything for cloth diapering for us. I am registered at 2 stores and 30%- 50% of each registry is inserts, covers, wet bags, etc. Did anyone else have unsupportive families, and how did that work out at your shower? 
It was suggested on another site that I register for the type of disposables I would want to use also, because people will buy disposables even if I say we aren't using them, and that way I won't end up with a bunch of pampers that I just flat out wouldn't put on him even if we didn't use cloth. But I don't want to encourage anyone to buy disposables at all. Help! 
(I am really not trying to come off as ungrateful- I know that people are buying us gifts because they want to not because they have to. This is a surprise baby and we are not well off financially at all, and the more items we are gifted and don't have to purchase ourselves, the better off we will be)
