Try to water the plant entirely, spritz the entire plant and water the soil line thoroughly. At times, there are tropical houseplants much more water and humidity needy. Then make sure you position it in just one area, where it will get bright indirect light. Do not move it around often. Got to allow the plant to acclimate.
Watering indoor plants does not mean doing it daily. The root zone area needs good airflow too and dry out time is affected by various factors like the type of container in use, light levels, airflow around the plant. Glazed container will hold water longer, so even if the top part of the soil seems dry, the soil below is still damp. Since it is a small container, you can compare the weight of the container before and after watering. If it still feels heavy after a few days, delay watering. Or use bamboo skewers, if you stick it in and comes out wet, delay watering.
Also what light orientation is there at the window sill? Your plant is more of a low light plant, so it will not like too much direct sun.
