It's going to be hard to start off because a lot of the jars have fruit in them to 'disguise' the taste of the veg and the baby enjoys it because its sweet, I don't mean that as a criticism, but that is why your dd is spitting out your homemade efforts.
It can be fixed though, so don't worry! Children dont (very very rarely) starve themselves, it's going to be a rough week or so but personally id go cold turkey on the jars.
Dd eats what we eat, so tonight its Shephards pie, il make it with a baby stock cube, portion out hers, then add the gravy thickner (which is salty) to the remaining which is what we eat. When I do the mash il mash it with butter, portion off dds, then salt and pepper our portion that's left.
Il then leave it to cool, mix it together with a bit of water to loosen up the mash, and then freeze it in ice cube trays. Once frozen pop out and store in freezer bags.
When it comes to reheating, my dd (2yo) will have 6 ice cubes, I put it in a bowl, in the microwave (frozen) for 1 min, stir, 1 min, stir.. Keep going until it's bloody boiling ie- painful to touch! I loosen it again with a little more water (cold) which helps it cool down, leave for 5-10mins then feed!
It also means I've always got meals ready in the freezer if we arnt eating until later/ having a takeaway etc!
Pm me if you want :)
