Thank you all for your ideas!

I meant the pouches, I have become unable to open.
But with one of the ideas here, I used a big scissors with fat handles, and was able to cut off the whole top,
straight across,
and then, spoon out the contents, to eat it. Thankfully.
I thought you would like to know my update on it, and I wanted to thank you all, again too.
I will use some of those jar ideas, also, in the future.
My straws are too thin. To use for pureed food to go through. Would fat straws of some kind work?
But for now, those hints helped me a lot.
