It is good to remember that when you are exclusivly BF you are their source of water as well as food. So on a hot day, you may find your baby a tad more thirsty and want to drink more... When you think of how often you have a drink of water on a hot day, every 2 hours does not sound like a lot. I personally think that 2 hours in Summer time is fine, maybe in winter you could try to stretch it out, but I would not try in Summer... (Just my personal opinion). Good luck with it.. In a few more weeks you will probably find the feeds stretch out anyway... mine did!
