cot

Nope not necessary , you can get a good quality baby mattress instead.

Huh then you want to run the risk of SIDS by sleeping with the baby?

Mine slept in a playpen for the first 2 months then we coslept

not necessary in my opinion but good to have one

I didn't use cot, i co-sleep with my lo instead.

Good for training baby to sleep himself

Hey, Yes so think it is good to have

Depends. But it is safer to use cot.
