First born

I'm assuming hammock = yaolan? If so, that is actually recommended for use only from 2-3 months old onwards when they have head control and are stable enough. I'd say this is something that also varies for babies. For example, I prepared a baby cot for my son but we ended up co-sleeping since he was born - he's 2.5 years old now :)

best let the new born sleep on the bed. otherwise when baby grown up, he/she will not be able to sleep if he/she was placed onto hammock during younger days

From young start training your LO to sleep in Bed. Hammock for me is temporary maybe just to make them sleep. You don’t want your baby to get used to it.

Bed. Hammock restricts baby movement and does not support baby’s spine

they say that a stable cot is best but my baby sleeps in yaolan

prefer bed, just keep the bed clear from objects and pillows

Bed. But my mum use Hammock in the afternoon.

Bed. Safer and I felt is better for backbone

Hammock but make sure it’s secure and safe

Baby cot, sleep on their own
