I've just heard that my sister's worrying that her 15-month-old daughter has been adversely affected by wearing bulky cloth nappies - apparently she's a bit bow-legged and flat-footed, and the people at her nursery have expressed concern that she walks a bit funny and seems to fall down a lot more than the other kids (who presumably wear disposables). I'm sure this is nothing to do with the nappies - I remember being concerned about the bulk between his legs making it more difficult for my Bumble-wearing ds to walk, but he never showed any problems and he's not at all bow-legged now!
I think she's made an appointment with some sort of doctor to look into the potential problem, but she's convinced it's down to the nappies and I'm worried the doc will say 'oh yes, no doubt it's that' (though of course s/he shouldn't jump on the 'easy' answer!). I've been trying to do some research but am having trouble coming up with anything concrete - I've seen lots of vague references to cloth being beneficial for babies with hip problems but nothing I feel is worth passing on to her. Has anyone looked into this issue? I'd appreciate some pointers to articles or something that I could show my sister, so I have evidence to back me up.
Likewise, if anyone knows of evidence that bulky nappies can be harmful to some babies, I'd be interested to hear about it. Thanks!
