Hello mums !
As I was browsing the parenting section of my Oxfam charity bookshop I came across an old copy of Dr Spocks guide to early childhood...so old that it stills recommends to put your baby to sleep on its tummy rather than on its back, which is a major cause of cot death. I mentionned that to them and they've put it away...you never know : someone might buy it and not realise the advice is wrong (although the awareness is hugely out there now). In those old books there might be other pieces of advice that is not relevant anymore or proven to be dangerous...
If you happen to have a charity bookshop close by, have a look just in case...
