at daycare? I did yesterday! It was raining, and I was in a hurry to get home. I had her car seat, umbrella plus a cover blanket in my hands and I put her bag of bottles down for a minute to strap her in, and I walked out the door without it. And I never realized until it was time to wash her bottles later in the evening! We had to go out and buy a few more bottles because we dont have enough spares of that type of bottle
