My baby is 8 months I try to let her sit by herself but she goes forward or back can’t balance her self in a sitting position. Also she isn’t crawling I just started putting her on the floor 1 month ago I’m also buys with work not really time for tummy time. So when I put her on the floor she will go in circles like twist her self and follow me but she’s still in the same spot and she goes in her walker and stands but won’t stand in her crib or nothing! Idk what to do to even help her sit up. Just something!
