Next month we're taking a road trip with our LO to see family and friends. We'll be away for almost 3 weeks and staying in hotels for a lot of the time. How would you suggest I bathe her? If it were a short trip, I would be fine with sponge baths, but since it's a long trip in the summer, I feel that she needs proper baths. Neither I nor DH feel comfortable taking her in the shower with us since she's already over 14 lbs and will be bigger by then. I was looking at portable bathtubs but every one I've seen has some bad reviews that make me uncomfortable. Any suggestions?
