Thanks Heather for your advice!

So maybe if I put on a singlet, a Bonds wondersuit and a waffle wrap my little man will be warm enough for September? And then I can just tuck a blanket over the top if needed. And then I can buy a summer weight sleeping bag for when he hits around 3 months...

Thank you so much for the offer of the wraps - I got a good supply at my baby shower - so no need to deplete your supply. But it's very kind of you. (Hope you can make it tomorrow!)
