My carriers: Manduca, sling and woven wrap. Couldn't live without them!
Also DS' amber teething necklace, he's almost about to cut his first two bottom teeth (8.5 months) and I can count on my fingers the amount of times I've had to give him medicine/bonjela. And MCN'S Love not having to spend money on nappies every week! Oh and definitely swaddle sleep sacks!
Waste: Although I love it, my Maclaren XLR that my Mum spent $800 on rarely gets used. Also the Bumbo because by the time DS was old enough to sit in it, he couldn't fit!
