Coming to four months old baby still need swaddle to sleep

Yup that’s fine:) only when baby starts turning/flipping, should you definitely remove the swaddle, to avoid suffocation (because they can’t lift themselves up while in the swaddle if baby accidentally flips onto the belly)

Actually you can start reducing the swaddling frequency gradually and the baby will get used to it :)

No need. I only swaddle my baby up till 2 mths. But it's actually up to you.

Still can swaddle they feel more secure.

I stop at 2 month plus
