wizadora, I'm a full time working mum too. All I can say is get a Babycook. It has literally saved my life. you just bung the veg in it, it steams it and then it's also a blender so purees the veg in the same water so keeps all the vits. If you want to put meat in you just cook the meat normally as for yourself, then bung it in at the blending bit with the veg.
don't know if this helps but I give DS of 8 months stuff like:
tiny pasta with a veg sauce (random veg just literally chopped up and put in the babycook)
whatever we're having, minus salt, blended.
mashed potatoes with tinned tuna squished up in it with plain yoghurt
pasta, tinned tomatoes and cheese
oat porridge with fruit for brek
then whatever veg with pureed chicken, pork or whatever.
red lentils (10 mins to cook in a pan), mixed with carrots or whatever veg sauce.
I have loads of little pots, make quite a lot then freeze some. Defrost in fridge overnight and it's quite safe for the next day.
I cannot recommend the babycook highly enough cos it just does it for you. I really think it's worth cooking stuff yourself cos you may be influencing them to have a taste for healthy fresh stuff all their life. can't you tell I'm also a 1st time mum!!
