10 month old waking up too much!

My LO is 10 months old and has never been a good sleeper. Naos for 10-20 mins twice in the day, very active crawling and trying to walk but nighttimes are becoming difficult....she goes down no problem between 7.30 and 8pm but will wake several times in the night sometimes not awake long and some nights she's up every hour and takes forever to re settle. She's in her own cot in her room and has been since 6 months. She's on formula milk and only uses as abit of comfort in the night. I sing and pat otherwise. Looking for ideas as it's exhausting and would be over the moon with 1 night sleep!
