C will pretty much eat anything and everything!!
Banana's are supposed to be good for both constipation and loose bowels. I read it somewhere but can't remember where, sorry!!
I'm assuming you are in the early days of weaning?? Here's a few that I have in the freezer ready for C:
Carrot and parsnip
Carrot and potato - C loves this!!
Butternut squash
Sweet potato
Cheese and onion pie - basically, grated cheese mixed with mash potato and a wee bit of boiled onion.
Baby bolognese - bit of lean mince, plum tomatoes and onion blended and some spaghetti chopped up small and mixed in.
Mince and mash - with a wee bit of low salt gravy and blended them mixed with mash.
Lentil 'soup' - carrot, lentils, parsnip all whizzed together to make a thick 'soup'.
Potatoes don't blend well - go like glue so I just mash them with a bit of unsalted butter and milk until creamy. C has had smooth yoghurt, fromage frais, ready brek, stewed apple etc.
Best thing to do, I've found is just to try something. If LO doesn't like it, leave it for a few days or so and then try it again. C has had some very wierd and wonderful concoctions and enjoyed them more than the more run of the mill. Root veg is usually good as it is naturally sweet and if you lightly steam, then they can be used as finger foods too!
Good luck and enjoy!!
