My 22 month old DD has always since 9 months of age gone to nursery on a Thursday and Friday . She stays with me on a Wednesday and is with grandparents on a Monday and Tuesday . We recently went away on holiday for a week and since our return she has gone into a tantrum on the way to nursery, shouting no nursery and sobbing uncontrollably , she then vomits on arrival at nursery. Apparently after 5 minutes of me leaving the nursery tells me she calms down and us fine although she goes now favour an earlier nap . I have been pregnant and gave birth last week , do you think this could have affected her behaviour or perhaps because I have been on maternity I have spent more time with her than usual ( grandparents have not had her. ) ? She always used to love nursery and I can't bear her being so upset every time she goes not to mention embarrassed by the daily vomiting all over the nursery corridors ! Any advice on how I tackle this or theories on why she has started this ?
