Good! Used the same exact omni 360 mesh since baby was 2 wks old. I like how it helps to reduce my back pain frm carrying baby. It can get a lil hot due to our warm weather but my baby can still sleep in it. I only use it when I need to bring baby out to buy stuff for a short while. Anyway as with all carriers, the general rule is not to let baby stay in it for more than 2 hrs. So if ure using it just for a short time should be fine. But if ure looking fr sth more comfortable for baby because some babies love to sleep in carriers, try Konnybaby. But it's advisable to probably buy when baby is out because not all babies like to be in carriers.
