15 month old constantly waking up

Alicia • 24 living on long Island, Ny

So for the past two weeks my son will wake up and cry to be under me while sleeping . I even bought him a toddler bed to see if he likes that better . He fell asleep for a few hours and still had a fit when he realized I wasn’t there . I’m 32 weeks pregnant so having him sleep in my bed is very uncomfortable . Any suggestions ?
