Comparing my baby to other babies

I know it’s wrong & you’re not suppose to do but I can’t help but compare my baby to other babies. My daughter is 11 months old and she’s so smart! But I can’t help but get a little jealous when I see babies her age (& younger) walking! She stands for a few seconds to dance but she has yet to take a step & honestly it gets a little frustrating especially since I try to help her balance and take a few steps but she gets annoyed and cry. I know it’s wrong so please don’t bash me. I just need to get it off my chest and maybe you guys can give me some advice or let me know I’m not the only mom that feels this way
