Hey Lisa, so sorry! Didn't mean to make you feel bad! We need to try things before we know what works The only boosters I've ever bought are from Baby Beehinds and Bubblebubs (online). They sell them in either squares (trifolds - where you fold them into three, funnily enough!) or strips, kind of like oversized sanitary pads. I mentioned the microfibre, which works well as a stuffer (and is very cheap and easily accessible) but unfortunately it can't go against bub's skin because it will dry it out. However, if you are looking for a cheaper option, you can get them and fold them inside the nappy perhaps? Not sure, as we only used flannel for a very short time, so I've no idea about folding flats... GL with it, and keep plugging on!
