Hi - my 7.5 month old had been whinging and whiney ALL day for a few weeks now. It’s driving me a little mad. Even at meal times she does it in high chair and purses lips and refuses to eat. Playing she just lays there and does it. Down for a nap she’ll do it for a while before falling asleep. She seems so unhappy. The only time she doesn’t do it is if I’m holding her and walking around. She’s not teething as is fed (with milk - I’m struggling to get her to eat solids) and clean nappy etc so not this. Anyone know why?
