Maia's first day to daycare (she is a bit over 18 months)

Preparing for this day, I have taken Maia into the starfish room few times so that she gets familiar with the staff. However, I still a bit worried about leaving her there by herself for the first time. We talked to her about the daycare and got her items marked.
And the outcome is ....Maia was happy to say byebye to us and only cried a bit. On the contrary, Zoe was a bit unhappy and became more clinging to me as she noticed that we put more attention to Maia. She even thought the whole day when she was in Dolphine, I was with Maia in the starfish room. Conculsion is we should have prepared Zoe as well.
