Baby sleep


Please help me. My baby is 9 weeks old and has reflux. She would only ever seep in my arms or on her stomach but the past few days she will only sleep in her swing. She fell asleep in my arms and woke up crying but I put her in her swing and she fell back asleep. Do you think something is wrong? I feel guilty because she sleeps for 5 hours in the swing when she has only ever slept for 2 hours most before. I'm just very worried about her. Any advice?
