Am doing BLW with my 6.5 month old, but paed has told me to avoid wheat for a while, which is a right pain when it comes to pasta. However, the colourful corn+vegetable fusilli you can get in Holland and Barratt has gone down very well - no sauce yet, but will try the philly trick.
As finger food I give my DD plain penne as its easy for her to grip. If im giving pasta as a meal to be spoon fed I use soup pasta as its small enough for her to chew and serve it with a sauce. I usually make a tomato, cheese and veg sauce and blitz it in a blender until smooth. Then freeze portions of the sauce to be used when needed.
