For me the catch with BGs was that my DD outgrew them at about 2 years old so they were not birth to potty (BTP). I did convert some of them from velcro to poppers a few months ago and she could fit in them again, but she just potty trained at 3 so that was that
....and to be honest as BGs are so slim fitting I struggled to get the absorbancy I needed to make them a viable nappy for dealing with older toddler widdle. They became one of those nappies you use between bath and bedtime etc. From about 10 months I boosted both DS and DDs BGs with an easy peasy hemp booster.
I am re-using some of her BGs on DS (the non pink ones anyway) but had to replace the leg elastic and the velcro. My BGs were my workhorse nappy (as when they fitted, they couldn't be beaten for reliability) so got pretty heavily used and with this in mind I think it is a bit unfair to slag BG for making the v4s with easy to replace elastic as I think it is aimed at those who use them second time around / use them very heavily. I'm very happy with my BGs and think I got way more than value for money out of them.
I'm looking forward to the v4 BG when it arrives in brights as pastels are not really my thing. If you go for BGs I would recommend you get some popper ones for when your baby learns how to undo velcro and also because the fit seems to be bigger and they will last longer.
The European stock of BGs is made in Egypt though, so would also recommend Tots Bots as a good UK manufactured alternative. But my personal view is that they make great 2 parters (strechy bamboozles are fab) but their All in Ones / Twos don't match BGs for reliability. And also, while BGs may be imported, a lot of them are sold by WAHMs so you are supporting them too.
I'm also more of a functional fan, especially as I don't like a lot of patterns, but I do think every cloth bum should have at least one "show-off" nappy. Don't under-estimate the power of a cute fluffy bum to convert others to cloth, or at least to get them asking / the conversation started. Blueberries are nice and trim (although again imo, not as reliable as BGs) and I would also recommend WeeNotions. DS's show off nappy is a weenotions BTP pocket in navy with a monster embroidered on the bum!
