For the past few weeks I havent been able to sleep. I have a queen size bed and sleep in the middle between my 3 year old who moves and twists and turns all night ad also sweats and gets all sticky and my husband whom is 6,0 about 260 pds. im 19 weeks pregnant and im so uncomfortable, I wake up every few minutes and sometimes just stay up 😩 ive been thinking about getting my son a toddler bed but my room is sooo tiny. I dont know how im gonna make it so that it fits a crib, a toddler bed and my bed! I just wanna sleep !!!
