Sleep

My almost 7 month old baby girl has been giving us a hard time putting her down to sleep at night. her bedtime is anywhere between 630-730. I'll nurse her and she usually will fall asleep in my arms shortly after. I hold her for about 10 minutes or so just because she has reflux. I lay her in her pack and play and not even a minute later she wakes up and starts screaming/crying. I wait maybe 10-15 minutes to tend to her but she gets herself too worked up to let it go. I pick her up and she falls right back asleep. I have to repeat this about another 2 times until she stays asleep. this has been going on for maybe 2 weeks. The routine for bed has stayed the same. I'm going to be transitioning her to her room for sleep in a few weeks. Not sure why shes been doing this. Anyone else experienced/experiencing this ??
