I don't have any scans but I do have some comics.
1987 Comic #1
Baby Lucky and Spike find a magic window and go through it. They hear crying and find dozens of little pixies who were pushing and pulling a buggy towards them. The crying was coming from inside and the Pixies them that they brought them a present for Spring and to "Take it away, please do"
They push the buggy back through the window into the castle tell the adult ponies what they were up to and said "We met some pixies and they gave us this present. Look, a new friend. She's called Baby Cuddles!"
1987 Issue #3
Baby Lucky and Spike head over to the nursery with Gingerbread and along the way find a strange tent that has Gypsy inside painting. When suddenly the #13 appears and floats over to Baby Lucky. Gypsy tells Baby Lucky that 13 must be his lucky number and today is June 13th. They rush to tell the other babies in the nursery and they all grow exictited. They think that since the numbers appeared while Gypsy was painting they should so some painting too.
Baby Lucky paints 13s on the paper and since it stopped raining he then decides that he wants to go outside to paint...
He runs into Gusty who wanted to borrow some paper to make herself a nurse's cap. Since Lucky had paper in his bag he empties it out to give some to Gusty and she asks him "Who drew these tiny ponies?"
"I don't know," replies Baby Lucky. "I think I'll trace them, they're nice."
Gusty then makes a nurse's cap while Baby Lucky traced the pictures.
"Now there are four tiny babies." he said to Gusty.
"Oh, you've colored them in" said Gusty. "They do look sweet like two sets of twins. I'll draw something for them."
"That's nice, Gusty," said Baby Lucky "Draw something for the baby unicorn babies that lilac one is a baby boy," ???(The lilac one Baby Lucky is referring to is Sniffle's from the Sniffle's and Snookums set, this is news to me that it's a boy.)
Gusty then draws a bassinet for Dibbles and Nibbles and a Stroller for Sniffle's and Snookums and she wishes they were real so she could be their nurse. Baby Lucky wishes they were real too and then the tiny pegasus twins flutter thier wings climb into the bassinet and then come off the picture
Baby Lucky tells them that the pink one is Nibbles and the other one is Dibbles they take them into the nursery and he wonders if Sniffle's and Snookums would come alive as well.
When spike asked if he liked the other ones better? Lucky replies that he gave one of them a boys name. He called him Sniffles. And Gusty hurries out saying they have the other set of twins in the nursery.
I think Baby Lucky discovered Baby Half-Note as well on a lost island if I remember right - can't seem to find that comic or book right now...
