Letting baby sleep in swing?

Do any of you mamas let your LO sleep in their swing at night? She’s up every 2 hours.. she won’t sleep anywhere but my chest and nap in her swing.. I try her crib and play pen and the only place she will sleep is in swing and on my chest. I’ve been sleeping with her on my chest at night but I really don’t like doing that.. is it safe to let her sleep in her swing at night? She’s almost 3 months
