@stay_tattd4_lyfe My son was born at 31 weeks. He had issues digesting dairy at first, but he grew of that and he could have dairy by 1 without issue.
On his actual birthday he was thrilled to completely demolish his cake. He ate some, he mashed some, he got it everywhere, and ended up crawling through the remains. We had him outside on a blanket. It was hilarious. The cake had sugar. Frosting had sugar. He did eat a decent amount, but the vast majority ended up on his hands, face, head, clothing, legs. Honestly it was more a sensory activity than an efficient way of ingesting calories. Zero regrets.
It was a small smash cake, about 5" across. He maybe ate 1/3 of a cupcake worth of cake and some frosting. He might have absorbed more sugar through his skin. Haha!
