Failure

Am I the only one who feels like a failure when it comes to parenting? My baby is 2 months and I still have no idea what I'm doing. I feel so dumb. My MIL puts so much pressure on me too and it just makes it worst. I still feel like I'm going through this never ending cycle of guessing what my baby needs when she cries. I get mad at myself because I am getting frustrated. Ugh this is so hard. When does it get easier???
