I always bought them at Kmart and Best & Less when kids were smal;ler. When they become older and you still would like a sleeping bag, ErgoPouch has a great variarity in thickness and sizes

we used all different brands! i had expensive one that i think was an ergo one because my daughter had hip dysplasia and it fit her harness in it, but after that i used kmart, best less, target, bonds and i think i even had one from aldi! it just depends your bubs my daughter couldnt use the polar fleece ones becuase she would over heat where my son could use any!

We bought a sleeping bag from Aldi when they have the baby sale. Also look out for Baby Bunting’s sale during the spring/summer. I bought Love to Dream sleeping suit with 50% off. They didn’t have it in their website, so you have to go to their store to look for it.
