Is night wakings normal 3 year old

My LO has always struggled to sleep well. She will sleep great for a while then it’ll get totally messed up again for seemingly no reason. We cut out naps about three months ago and that helped, she was not sleeping at night if she had even a short nap even though she still acts tired during the day. So it just seemed like that time and she’s getting older and she’s been sleeping great but still says she’s tired often during the day. This week she has woken up three nights. Once at 4 am and didn’t go back to sleep until a nap around 9 am. Then at 1 am taking an hour to get back to sleep and now 2:45 and it’s been an hour and a half and she is still struggling to get to sleep. Is this normal? I just feel like she’s getting older and I thought cutting naps would be the end of our sleep issues. She will be yawning but acting wide awake. She gets plenty of energy out during the day and normally we are outside a lot but it’s too hot here right now. I understand the occasional off night but three times in a week? Should I be concerned there’s something more to this?

I also have a teething baby that wakes all night and I’m exhausted.
