I want to transition my 3 month old to a pack n play soon. She hasn’t exceeded the weight for her bassinet but she moves a lot and has been waking up with her face against the edges. Because she’s 3 months old I don’t NEED a pack n play that comes with a little seat or anything. I’m hoping not to spend much more than $100. I want something that is comfortable for her to sleep in as this is what she’ll be sleeping in for the next 9 months until we move her to her crib in her room. What do y’all recommend? Also, do you recommend buying a mattress separately or do you just use the one it comes with?
