My partner had paternity leave after I gave birth, and then 'additional parental leave' (where you split your maternity leave), which applies to heterosexual and same-sex couples alike. I am the main bread inner and self-employed so no decent maternity package. Now she is self-employed too, she qualifies for neither.
We had a woman at work who took both maternity leave and paternity leave. Once for the birth of her daughter, the other for the birth of her partners daughter. I'm not sure its any different to heterosexual couples.
We were chatting to one of our lovely Family friendly members' HR folks yesterday and she was wondering if anyone on MN had had any experience of being offered parental leave when their partner had a baby and how it had been handled. She had been asked about it and just wondered if anyone had had experiences - good or bad - so she could learn from them.
