Trouble sleeping

Anyone else having trouble sleeping? My baby is almost 11 months old and I’m having a very hard time sleeping and it’s not always because of my baby. She doesn’t consistently sleep through the night, but some nights it is her that’s waking me up. But lately I’m waking up at 1 am and will just lay in bed for 3-4 hours just staring at the ceiling unable to go back to sleep. When I do manage to go back to sleep, my baby will usually inevitably wake up shortly after waking me up again, or my dog will wake us up needing to randomly go outside. My husband has been taking more of the nighttime feedings to let me sleep, but once I’m woken up, I just can’t go back to sleep for some reason. I’ve been consistently going on 3-4 hours of interrupted sleep lately and I’m losing my mind! Anyone have any ideas as to why this is happening or tips to stop it? I’m a stay at home mom and extremely stressed anymore, but the lack of sleep definitely does not help.
