please help! feeling like a failure as a mom

my daughter is 11 months and has started throwing tantrums if she doesn’t get her way she cries and i’ve given in a few time i don’t know how else to handle her if not me other people who take care of her sometimes give into her demands

also she’s been super clingy pst month and it seems to keep getting worse to a point i can’t even get up to get water while she can see me , she goes hysterical

im not getting much sleep she doesn’t want to be with anyone else if im not around

she’s not wanting to be spoon fed and only eat a few pieces of food if i let her feed herself

im at my wits end please can someone tell me there’s light at the end of this tunnel that this is just a phase

when i was pregnant in theory i’d do everything perfect i want to raise her to be a good kid and not spoil her but it seems impossible right now can someone with older kids tel me it’s possible and how to

do it right i can’t help but feel like failure as a mom
