Not needed and with 52 comments I bet someone has included them in the list of dangerous baby items. Mom of 5 here and beyond a crib, carrier, rocking chair, car seat, high chair, bouncer and pack n play most of the big stuff just takes up more space than they are worth. My best advice is to avoid anything that swings, vibrates, plays music and entertainment because baby will get attached to these things and traveling gets very difficult. It’s just a lot easier if it’s a human they look to for soothing instead of gadgets that break, need batteries, get forgotten or you don’t have room for on a trip.
