4 month old naps and eats

My 4 month old naps and eats in her bouncer she just loves it she's at the point she doesn't want to be held unless it's her night feedings she's bottle fed and formula fed she's growing out of her bouncer quite quickly I'm thinking what I will put her and after she goes out of it or do you think she will be at the point should be holding her own bottle crawling? Anybody else doing this also there's a picture of her below.
