Separation Anxiety 😥

Due to Covid me and my husband has to bring up our 9 month old baby . He will mingle with anyone the minute he sees them but when at home he wants me all the time!!! Not even dad when he’s upset 😭 he sleeps on his own in his crib .sometimes he sleeps back if he wake up in the middle of the night, sometimes he will scream and wants to sleep next to me . This been happening for last few days now . Don’t know what to do! This is a sudden change in his behaviour. Anyone else having the same issue ?
