Feel like its Abandoning my child

When my little one goes to bed at night ( she will 2 months Monday) I’ll feed her, read a bed time story play and cuddle and once she fall asleep I lay her in her crib which is next to my bed ( pic at bottom for reference) sometimes she will wake back up and look at me smile or just glance around the room. I feel as though if I lay down and just let her lay there and fall asleep I feel like I’m abandoning her by just letting her lay there and ignore her. Does anyone else have this problem or have any suggestions.

Her bed owlet monitor and my bed her was on her room but she to young to sleep in there along this is my first child
