Dracy, like mine & Anne's case, both hubbies & us are PR and we chose to give birth in S'pore, so no problem in getting M'sia citizenship, no need to get out of S'pore in order to get M'sia birth cert.
Newborn is allowed to stay 'free' in Singapore for 42 days, so within 42 days, if not intending to get PR status for newborn, then after getting M'sia passport, BB is just like any other 14days visit tourist ... if intending to get PR for BB, then within 42 days, must get PR application for BB .. of course photo, Birth Cert & passport must be ready at that time.
This procedure is applicable if either parents r M'sian and wanting BB to b a M'sian.
Of course if wanting BB to be a S'porean, then all these procedures can be opted out.
