Over the last 2-ish weeks, LO has started hating her crib/cot at night. Some nights (like last night) I was able to feed her and put her in her crib when she was asleep and she didn't make a peep for 2 hours. Then she woke up and wouldn't go back to sleep. She cried and screamed. Giving her the paci didn't help, I picked her up and rocked her back to sleep - put her back down and she was instantly awake. I tried this 3 times with the same result. Every night for the last 2 weeks she's been doing this. I've left her to cry but after 2 hours I couldn't take it anymore (she briefly fell asleep during this before waking up again). Last night, after 1.5 hours I took her into my bed. Her crib is still in my room so it's not a separation thing, she's teething but don't think thats really contributing.
Can anyone help? I'm the only one who gets up with her at night and it's hard when I'm exhausted. She hates the crib for her naps too but that's only developed since this started.

ETA: She will be 7 months old on Saturday.
