I used a spray bottle, and at the moment am using a ridiculously overpriced spray from Aromababy - smells soooooo good and I love the soothing bits for a newborn squishy's tooshie! When its gone we're back to plain water though. For out and about I have a smaller bottle.

Not sure if you want actual wipe recommendations too, but I have two sorts - bamboo ones that are quite thin but easy to use and do a good job, and itti bitti ones that are lovely and soft but TBH I find them a bit bulky for such a tiny bottom - will probably like them more as she gets bigger
