My lo is just over 2 and has been going to her childminder since she was about 6 months. She has always been settled and happy to go. A couple of months ago my childminder started looking after another little girl who is just under 2, no issues. The little girl has two older sisters that the childminder picks up from school on an ad hoc basis. Initially my lo got upset whenever the sisters were picked up but this has now extended to when the younger sibling is at the childminders and she can cry for the whole time they are there. The childminder has other children and my lo has no issue with any other child just the older two siblings. I obviously don't want my lo upset for so long, sometimes it can be up to two hours that they are there. I'm looking for suggestions on how I can help the childminder build relationships with these older two girls as we're both at a loss and instead of getting better it is getting worse
