I am considering buying a baby sling and am trying to weigh up the pros and cons, i live on a second floor flat,with no lift, and think it would be easier to have a sling to pop the baby in when i am just popping to the shops, and also to carry the baby down the stairs, with the puch chair to avoid having to leave baby on her own, obviously baby would be in a bouncer/cot if i left the room, completely safe. I would just like to hear your opinions on them as i have heard alot of arguements recently saying they maybe unsafe and which one would be the best to buy in your opinion,also considering i am on a tight budget, and would also maybe like to use one for breast feeding descretely in public.
