Sleep question

Sierra

My LO is sleeping really well the first part of the night- from about 9p-3:30a. She eats great (breastfeeds), gets diaper changed (1-2x) and she’s back asleep by 4:30.. .. but then I have to pump since I’m so full and she went so long... so I’m back in bed around 5ish.

But it seems like my LO is super squirmy, restless, and noisy this last part of the night! It keeps me awake (plus my DH leaves for work at 6:30).. and LO then wakes up for the day at 7:30! So I’m basically awake for the day at 3:30a! It’s so tiring!

She’s swaddled also and when she’s squirming it’s like she’s fighting the swaddle- but will wake up and scream if not swaddled...

Are other babies restless like this? How do you get back to sleep or get more sleep after your big chunk of sleep? Any hints?
