We use totsbots on Harry (14 months) and they're great, but we find them bulky as well, more so on a newborn. So we use them for naptime (when we put H in a sleeping bag without his jeans/trousers anyway) and for night (with boosters). We always buy the next size up in vests/babygros to go over cloth nappies and have got used to this now, but it was irratating at first as we had sooooo many tiny clothes that didnt fit. We use Onelife fitteds the rest of the time and pocket nappies for out and about. This works for us and we love using cloth nappies
You'll find out what works best for you, perhaps have another try when you feel up to it
