I use BM for MJs first weeks and they were awsome, already had BBH so progressed onto them when she was a bit bigger anyway. I have a friend that has used BM exclusivly, with her twin DS and then DD, for aver 18mths she had all three in them.
I use them as boosters with other nappies now, cos i only bought the newborn size.
totally worth it, unfortunatly i got addicted to fitteds and AIO AI2's!!!
