What a wonderful idea! My oldest son was a premature, born at 30 weeks. He pulled his tubes all the time. Soft toys you buy in stores are way to big or heavy for these little baby's.
It is now 20 years ago that he was born, and I remember that I was looking for something for him to hold, but I couldn't find anything suitable. Wish I had known this then!
I still have some of the tubes he pulled, and his first little sweater .
He's 20 now, studying at University, getting his driving licence tomorrow. Oh, how time flies.....
