Date night, night time in bed is for chatting and catch up on days. Messaging / calling during the days.

Lots of great suggestions here, seem too simple if your relationship is in direct straits tho

My first child was my partner, my kids are grown up and he’s still acting like a baby. I wish I knew then what I know now, I would have walked away before we had babies together

Practical suggestion: Go for a walk in the late afternoon/evenings. It’s easy one-on-one time. It’s not about having deep and meaningfuls, it’s simply time spent together and gives the chance for regular conversation.

Date nights. It seems so simple, but that time away from the children seems to relax hubby and allow us to really talk and create space to listen.

Also, sitting down and discussing and agreeing on what is important for both in a relationship is key. It helps to identify areas of strength and areas to work on together. Relationships, like all things need to be nurtured and worked on. We also plan activities and book them in ahead of time and also leave plenty of room for being spontaneous. Relationships should be enjoyed and should be fun.

I agree make time for each other, listen with interest when you share what’s on each others mind. Make an effort to go out together when someone else watches the kids. And when that fails have special time at home when kids have gone to bed

You have to have time together doing things you both enjoy or either enjoys in turn. Family outings are not just about the kids, make sure you all do things together.

We have always prioritised our relationship and spent time together sharing fun interests and nurturing our relationship. We have always organised time for ourselves, going out, mutual hobbies and interests, talking and respecting each other as individuals, partners and parents.

Thats a massive question.
I think you need to make sure that you have time alone to talk. Share the ups and downs of each others day and make sure you truely show an interest.
Some times life becomes all about the kids and you can forget about each other in the process.
