Glad to hear the propped mattress is helping T. Also good to hear that you got that diagnosis. What are you giving DS2 for the reflux?

Rainforest - a friend of mine at playgroup had her baby boy in a hammock for ages, and he slept really well in it. In fact, while most of us where saying we where getting up during the night, her little one slept thru. Perhaps try hiring one before you buy, just to make sure your little one likes it.
