In the SIDS website it says this about hammocks;
There is no Australian standard covering the use and manufacture of hammocks for baby. While we are not aware of any research on the safety of hammocks or guidelines for their use for babies, we are aware of case and injury reports documenting a number of hospital admissions of infants following a fall from a hammock and tragically 2 deaths of infants sleeping in hammocks in separate incidences in the USA in 2009.Babies sleeping in hammocks are at risk of incurring a falling injury. Babies should not be left unsupervised in these devices as they are not designed as an infant sleeping place."
Everyone is entitled to use what they want... but I don't think i will use a hammock, just not confident about them... not sure about slings... I haven't really thought about them, might have to research it a bit more.
My DH works away so I will be by myself every second week so having baby in our room is fine for the beginning, cause when DH is home he is not working, we have agreed to share everything while he is home as I will need the break aswell after being alone for a week, he is pretty good around the house now so should be pretty helpful when bub comes.
