Does anyone know if I use this for my baby to sleep in at night, can I keep the changing table part…

I would take it off

It’s a changing table and bassinet

While the baby is in the bassinet no but when the transfer to the actual mat in the pack n play yes.

I used it for my first born

I have the same model but the bassinet is only half size, so don't know how taking the changing the table would work @jujum

I left it on until my son started lifting his head up. It doesn’t matter if you take it off or leave it on, it’s really just up to you😊
