See it if You don't mind a very slow-paced show (90 minute first act alone!) with poor quality actors, many of whom can't sing.
Don't see it if You want a fast-paced fun romantic comedy, since this isn't it. Exhausting, poorly cast, way too long.
See it if You like the theme of babies and how they affect lives. A pleasant show is fine, it need not be great. Very simple staging is OK with you.
Don't see it if You are looking for earth shaking spectacular music and drama. Baby is not on that scale. The theme is pregnancy and its highs and lows.
