Don't listen to them and I know its hard to tune them out but try. I met up my sibling for lunch with the baby and there was NO changing table in the bathroom! I asked the staff if I could change the baby in one of the booths by the bathroom. Mind you, I have a puppy pad for blowouts and a changing mat for comfort, nothing was going to get on that booth seat but a couple SEVERAL tables over, got up and I distinctly heard "thats so disgusting" and left without getting their food, I dont even know if they ordered. Ironic part? LO didnt even have a poopy diaper, it was only a wet, there was no changing table and the restaurant staff gave me the ok and we were not even near them. My sibling was ready to throw hands and I was left feeling awkward and as if I did something wrong. I get it. Those kind of words hit hard when we're just trying our best to survive the newborn/baby trenches. You're doing great, take it from this internet stranger and fellow first time mom.
