Video monitor was great for us when we moved the baby in his room. Its pricy but worth every penny.
I have always used pampers unscented wipes and DS now 20 mths has never had a diaper rash even though he was bottle fed.
Mylicon drops were a life saver when DS started throwing up at 3 weeks. We started giving him after every feed and it helped keep his formula down. We still give it to him on and off.
