Trading Gifts

So me and my bf decided to do something different this pregnancy since it's our last, I don't know if it's a good idea or sound lame but he will be buying me a gift basket with everything I need for the hospital and I will be buying his stuff he need but we will not show each other what it is until we actually go.. I planned on buying him a pajama set, white tee shirts, socks, I don't know what it else to get him I need help!?
