I think parents are more involved now and also more aware, which is great. Before, all the responsibility was left on your hands now, they have a say positive or negative is great, they are participating.
You are the main person in that group. So. Basically you can decide to guide them through all your accumulated knowledge.
I keep always extras of everything so, no frustration arise from left things at their home, it is my job and I do it as comfortable as I can for my group and me. I do not let little issues ruin my days, the frustration is not worth it. Children come, children go, but my heart will always keep treasured just the beautiful moments we've shared.
