Baby and sleeping very little

My lo is not sleeping enough at night ... We start her bedtime routine at 7:30pm. Bath, story and feed to sleep. It takes her a long time to fall asleep as and gets really fussy and only falls asleep being bottle fed. Well last night she finally goes to sleep at 10pm. She'd sleep for 3 hours, wake up crying for bottle feed. Goes back to sleep in crib for another 3 hours. Wakes to crying. Feed and then only sleeps for 45 mins. Her total night sleep is usually only 6-7 hours. Should I be concerned???

During the day naps she is only able to sleep in her swing or bouncer ... But it isn't much.

Advice on babies night time sleep? Should I be worried she's sleeping so little at night?

Notes: she's bottle fed breastmilk

Sleeps swaddled with white noise.

We live right next to a high traffic car street on ground floor so I wonder if that noise bothers her, but pedi says babies sleep through everything?? She seems to wake up at slight sounds but have no idea if it's the car noises.
