How old is she?x
My kid's lightest meal is usually dinner too. Have you tried offering some dinner foods at lunch or breakfast time?
My baby was like that when teething
What time is dinner? Could she be tired?
She has 6 teeth currently and all came through between September and December. She's had nothing since then and while she does get red cheeks sometimes there doesn't seem to be any signs of any more. She's 13 months. We do breakfast about 8, lunch about 12 then dinner about half 4/5. I do it a bit earlier in case I have to give her something else.
Perhaps a good chart might help? I use this one but the weaning version but she could have a personalised food chart which might encourage her to tick off foods for dinner? It breaks it down into different food categories so this might encourage her (or her watching you do it together) to tick off different types of foods? I know she might seem a bit young but they taken in soooo much. More than we realise. I’ll link it here. https://www.etsy.com/uk/listing/1883715605/?ref=share_ios_native_control
Sound normal to me - could be teething?
