My first thoughts/impressions: I was intrigued and interested, then rebuted when I found out it wasn't about the general human babies. But it quickly changed to me nodding my agreement to this figurative take on it. However, at the end of it, I felt... dry. I haven't been emotionally gripped, sadly, because poems are supposed to make you feel connected... and yet I felt miles away. I re-read it thrice on different days, but still the same. (Though I'm glad you won a contest with it! :D)
Why I chose to read your work: the word 'baby' caught my attention seeing how I love children and the sweet emotions they make me feel. Then, when I saw it was a poem, I was thoroughly excited.
What I appreciated: that you chose to include every type of 'babies' in your work. Because it is true, a novel, a poem, a business, a child... everything you care about and put efforts into can be your baby, metaphorically.
What I think needs more work: It needs to be more profound in the choice of words because I didn't connect. We readers need to be emotionally pulled into it... I think the terms were too general, just skimming the surface of what could have been. I think if you chose words with more impact, depth, it would work better. :)
Grammar, spelling & idiomacy: there are only two mistakes I found. The first being 'well worn', it needs a hyphen: well-worn. The second probably being a typo: in the third verse, after 'your heart', the period is missing :O.
A little favorite of mine: I would have to say the third verse... I think it says everything about this poem and is the most emotional part of it. Yes, definitely this verse and its truth. The last two lines having tugged at my heart a bit, which was fun.
Overall: I appreciated the multi-dimensional meaning of 'baby' in your poem. It was sweet. I would have loved to relate deeply to it, but no real emotions were created in me... unfortunately. I suggest you work on that (this is meant very friendly). Also, I notice it rhymed at the second and fourth line of every verse, which is interesting. However, I would prefer if it rhymed at every line - I'm a sucker for rhymes :). But that is my personal opinion completely. Perhaps it would help the connection.
Thank you for sharing this piece.
