I try to do w/out changing my 4mth lo's diaper when it comes to dreamfeed time. But, because she's a tummy sleeper, she sometimes wakes up the next morning wet around her tummy due to leakage from the top of the diaper. So in the end, I do change her as her diaper's wet anyway. Sometimes she wakes up and other times, I manage to keep her asleep thru the change. Either way, it hasn't affected her sleep for the rest of the night. My only worry is that she may develop the habit of waking up at nights but I guess I'll have to tackle that one when and if it does happens... In the meantime, I feel more at ease knowing that she's nice and dry for the rest of the night!
