“Galaxy’s Child”
Geordi is looking forward to meeting Leah Brahms, the woman whose holodeck image he fell in love with, but the real Dr. Brahms is only angry about the changes he made to her engine design. Meanwhile, a space creature has been accidentally killed. The new-born baby thinks the Enterprise is its mother, and drains energy from the ship. La Forge and Dr. Brahms set to work to get the baby off the ship, but unfortunately she finds her idealized image in Geordi’s old holodeck program. They finally succeed by changing the energy frequency so as to “sour the milk”. The baby leaves the ship, and joins a swarm of other creatures of its kind. summary by Ex-Astris-Scientia
Cute! Again one of the better in the whole series for me. Excellent dilemma and maybe just a little too easy a solution. I would have preferred to see them drag this “baby” along to the nearest starship base instead. It would have made for an excellent pet. 
Also loved the rapport between Geordie and Dr Brahms 
I loved to see the real Lea after their holodeck romance. Very intriguing and - unfortunately - very true about a lot of fantasy relationships.
