Feel like I am a bad mom:-(

We had our baby's 4 month appointment today at 8 am and reached there 20 min late so they had to reschedule it for Tuesday.

My baby is going through this sleep regression and we managed to sleep at 3 am but I knw that shouldn't be an excuse!

I feel so awful! I feel like I m being such a bad mom! :-(

Please give me some tips or advice on how to manage everything!
