We got one for DS when he was about 6 mths. He loved it, we only used it once or twice a day for around 10 mins each go. It was brilliant in the afternoons when it was typically his unsettled time. They say walkers are bad too, infact there is probably someone somewhere that says almost everything is bad re: baby products. In other words I think our mothers intuition is often more trustworthy than the advice of others sometimes (even "professionals", I am very anti chiropractor tho so would never take notice to what they said). Btw, we have a large steel hook which is screwed into a beam in our living room opening, it came in the JJ box along with the clamp for the doorways. I have seen the stands/frames at toys r us.
