Hi mummies, i will like to know if frozen cube is healthy for them? I would like to start my LO with this method and can share with me what's the step of preparing this?

I will cook all in one pot like boil soup then blend it and freeze every week (Friday). Eg. chicken, onion,carrot in boil first then put green vege in last. Then blend it to thick texture put in container into serving portion. thawed a day before then with add in cereal to serve my lo. He can finish every time.
