我是乙方。

Wish you born a pretty baby and have a good time!
这样够了么？
有啥别的高大上的语句么？

Wish the baby is really yours

born改have，pretty 换healthy吧，good time 免了，生孩子是纯受罪啊。

have a good time

太生硬了，给人感觉是翻译机出来的 口语化就行了
take a rest
have a good time with your baby : )

Wish the baby is not black

MAY THE FORCE BE WITH U！

wish you take a lovely baby

enjoy this relief

用Congratulations！比较好，其他随意

Wish you born a pretty baby，这种生什么孩子有点隐私的话老外看会不会不悦，直接恭喜就算了呗

All the best wishes for you

Congratulations on your baby（这个最好是生完了）
或者
All my best to your little miracle

Happy birthday?

至于么？

没干过乙方的不明白

all my best wishes to you 就可以了 这种就跟中国人见面问吃了么一回事 没必要照样翻译

So glad for hearing the good news! God loves the baby…
以上是纯yy

best wishes不就完了么

简短恭喜一下就行了

All the best in the maternity leave

happy be dad

甲方是老外？生完小孩直接全职妈妈都很可能。

rest in peace

祝紧致
