The Imam doesn’t recite the Fateha properly, is my Prayer invalid? – Sheikh Assim Al Hakeem

I am a mother of 4 months old. Most of the time i miss my obligatory prayers due to my son’s crying. He hardly stays quiet on bed. If i leave him crying on the top of his voice & pray, that too is not worth as my whole attention will be towards my crying son. I am afraid for the punishment that i will get bcz of neglecting my prayers. I don’t know what to do.
