I feel like a shitty parent , please help

Christina

My daughter is 8months and has been trying to walk since she was 5 months , she’s taken falls and spills trying to walk but always cries for 5 seconds and then gets back up and today we came to my moms house and was walking in her walker & she took a spill and cried and my mom came and walked in and said “you can’t let her fall it was unnecessary” and I’m like “she’s gonna fall but she always gets back up” and she says “no it was unnecessary” I said “don’t act like I never took a fall as a baby” she said “you never did cause I never let you” and now I’m in the bathroom crying my eyes out because , her father just left and he’s 2000 miles away again , if I let her cry for more than 2 mins to take a piss , then I get asked “what are you doing to her, what did you do” and every one makes me feel like I’m messing up as a parent and I’m just mentally and emotionally tired
