Don't rush the process
Some people cope by blocking out those tough emotions during the beginning stages after a miscarriage. But with time, those wounds will open if you haven't allowed yourself to grieve properly.
You should take your time rather than force yourselves to bounce back to your usual routines too quickly. It's okay if you just want to stay home and grieve for a while until you feel better.
Accept each other's journey
People deal with grief differently because we're not all the same. One of you might prefer to cope by staying busy to avoid being overwhelmed by everything and the other might prefer journaling as a way of healing.
The process might look different for both of you and that's perfectly fine unless there are any major concerns.
Seek support outside yourselves
During such difficult moments it is a good idea to reach out to someone who can help you deal with what has happened. You can talk to someone close who has been through the same thing or even involve a counsellor or therapist.
You can decide to push through alone and counsel each other but it's much better to seek some healing from a third party. You can even try and join support groups that can encourage you whether you have experienced a single miscarriage or multiple.
You don't have to go through this alone as a couple. Reach out for help.
