This series finally came up on my ever-growing "fanfic to read" list. Absolutely loved it! The first chapter was quite heartbreaking and sad, but the ending was very adorable and wonderful. I felt that this was a very excellent backstory to Trixie's past.
Perhaps the struggles they go through during the pregnancy, being parents, and the struggles the child has for having two mothers, things like that maybe, thats that can test their lover for each other
I imagine Pinkie as Trixie's "lovely assistant" in this one. Still unsure about if I'll even do a follow-up, but fingers/hooves crossed I think of something good. I have drawings and two other series in the meantime anyway.
For your first attempt, its pretty good. The only real knit-pick I recall is that it seemed a bit...odd to me that they were just told how the other feels. It kind of takes away some of the shipping tension.
On the other hand, it set up Trixie for a funny little joke at the end, so...
Well I think it's a great change of pace. I have seen very few stories of Trixie with another pony besides Twilight. No I don't hate Twixie shipping at all. I love seeing a change in pace every now and then.
