Any ideas?

My 5 1/2 old baby has been waking more frequently lately. She normally eats 2 bottles at night and lately it's be 5 and night. Which is ridiculous. I do still swaddle her and she sleeps in a swing. I'm thinking because of her recently becoming active (scooting everywhere) she is waking to play. With my first daughter i went through the same thing and I got so frustrated I switched her to her crib and in 3 days she slept all night and woke up maybe once to eat. Does anyone have any good ideas I could try before having her cry it out?
