Wasn't sure where to put this! My DC is 19 months old and a bit fussy, always has been, right since the start of weaning. She often asks for food when she is bored or tired, and she has a terrible sweet tooth and doesn't often know when to stop if she's eating something sweet like fruit or cake.
Her DGM looks after her one day a week and we are so grateful for this. They are very close and she loves being with her nan. DGM has always struggled with feeding her in various ways ever since she started childcare for her. We have always left her to it. She had a fairly healthy diet there and it is only one day a week and I don't think you can expect people to care for your child in exactly the same way you do, especially when they're doing you a huge, free favour.
The last month or two though, DC's eating at her DGM's has become...not great. And I think this is because DC has now realised she can play her nan a bit! Or is she too young? For example, refusing to eat lunch and then promptly eating two packets of raisins and cake instead. The other morning she had breakfast at 9am and then at 11am asked her nan for food who gave her an egg and raisins. It's not only the food itself which is sometimes an issue (I don't mind her having some raisins and even a bit of cake with her lunch if she's otherwise eaten something decent), but also the erratic eating at weird times which then means she doesn't eat dinner because she's had two yoghurts and fruit at 4pm etc.
I can't decide whether to speak to her about this now (gently!) or whether I should continue to leave it as one day a week isn't going to harm her and I am grateful for the free, excellent quality childcare.
