From the opening shots of wriggling white tadpoles swimming through a neon womb, Amy Heckerling tackles motherhood humorously and head on, alternating between mucky-diaper realism and bright fantasy. Baby Mikey comes complete with snappy personality and the streetwise voice of Bruce Willis. Slapdash mum Mollie (Alley, a convincingly falliable parent) falls out with the already married father (Segal) just before the birth, and is tended instead by a taxi-driver who ferries her to hospital. Baby instantly likes the look of feckless cabbie James (Travolta), but Mollie is resistant to true love, especially when her mum (the admirable Dukakis) is striving to fix her up with someone more respectable. It's what-is-a-good-father time. Of course, we know it's the guy that's poor but fun. Heckerling directs this dippy but delightful film with a light, zany touch and a reasonably low yuck-factor (dribbles notwithstanding). Particularly cute is the way Travolta sends up his most famous role in a parodic disco dance routine.
