For our DS we had a cot, hammock and bassinet, he was in the bassinet and hammock until 2 months and then the cot and hammock from then on, we stopped usuing the hammock all together when he was about 5 or 6 months old.
The hammock was lovely though! I used it when he wouldnt settle or for some of his day sleeps, but for night time and long sleeps he went into the bassinett or cot.
I got my capsule new off TradeMe and it was fantastic, and safety approved, DD has just gone into her safe n sound carseat now at 7 months, DS went into his at 7 weeks as the capsule we had was crap, I got it off a friend and didnt realise it had expired
