6 months old, needing some tips

Sandra • mommy to a beautiful baby girl and baby boy

my daughter hates tummy time no matter want I do, she even can't roll over yet. I'm worried her doctor keep telling me to push more tumny time as soon as she lays on her belly it's horrible screaming to were she cant breath. I try to do tummy time just a few minutes I will repeat it through out the day. I just feel so bad that she gets so worked up. all she wants to do is stand or sit up.
