Missed Appointment

Got up 2 hours early got ready for my doctor's appointment as we are 32 weeks. My 2 1/2 year old still in bed watching her cartoons then decided she was hungry she only snacjs after getting up. Made breakfast and told her I need to get my coffee and get the cat some food. Instead she whining and crying because of it. Then told her to finish up so she can get dressed and take her to my mom's- she doesn't like going there. Took her forever to finish and I ended up cancelling my appointment because I couldn't make it on time. Went and did other errands instead. I tell my husband I blew off the appointment and rescheduled because our child was taking forever this morning. He told me it was my fault and should've known better. He didn't even let me talk. Wasn't 2 hours long enough? Am I at fault because my kiddo took her time to have breakfast?
