The last couple of weeks my 18 month old has started to cry and have a tantrum when i pick her up from nursery. She even runs away from me sometimes. It up sets me and i think it make me look bad in front of the nursery staff. What am I doing wrong? She there 2 and a half days a week. Shes not a cryie baby when at home, so i dont understand. Am I not giving her enough attention?
