Motherhood 😩

As a FTM I find it hard some days & I feel extremely guilty. I didn’t know better but to rock my baby to sleep after feeding, i didn’t know i had to lay her there & she’ll sleep on her own. Everyone tells me it’s wrong & that I got my baby used to that, she’s 13 weeks today. Yet, I heard that it’s good for their development & that they’re too small to “manipulate you”. I get so nervous to go out by myself so I just don’t, sometimes she starts crying & not sure how I can soothe her. She hates pacifiers & she dislikes the baby wearing I have since her head is basically in the air. Any tips are extremely appreciated, even constructive criticism. TIA
