Hi - I take Noah out all the time - we go somewhere every day (out for coffee, long walks, shopping, out for dinner etc) and he has even been to a wedding... I agree re not having the bub passed around - i was at a lunch on sat and lots of ppl held him and he was so unsettled when we got home and also i missed him LOL!!! I think if your bubs is ok going out and you enjoy it, do it as much as you like and what works for you both.
WTG withthe b/f as well, this was something i was also nervous about so i also tried it from the start and i am getting more and more confident with it now.
