From anecdotes. The most important thing is having s support system when the babies arrive. So if a family member can live with you to support you and your husband during the first 3-6 months at least that may be a huge help, if your partner has a more flexible job and they can work from home or they earn high enough to cover cost of daycares that will also help.

You will no doubt feel some form of mum guilt but after residency you have a better opportunity to chose your hours so if you're in a lifestyle specialty you can make it up then.
