Am I being sensitive or rational

So, I work full time at a daycare with a bunch of women (half of them mothers). My daughter is 9 months. She is breast fed. Ever since I went back to work I’ve had to pump and 9am and 12pm. Tell me why 7 months in I still have to ask for them to send me someone to relieve me for 15 minutes to pump every time? Like it’s a daily routine. I feel like it’s so rude of the women, who are mothers, running this place to make me beg to go feed my child, who is attending the daycare. They seem annoyed every time I ask to have someone sent in, but like, you knew it was coming so just save the hassle and have it ready??? Am I being over dramatic about this or would you be annoyed 7 months into the SAME routine to ask?
