Do your adult children maintain similar contact with both of you?

My ACs have always spoken to both of us, when my darling man was alive he and the boys would chat about their work & football and discuss anything that was bothering them where as my DD would keep any problems from her dad and discuss with me.
We keep in tough every day through messenger DD visits 4 times a week and boys call in on their way home from work twice a week to check if I need any jobs doing they keep in touch with each other via WhatsAp on a daily basis.

We have separate families, mine are in touch daily via WhatsApp but my husband's family only get in touch for something specific. He is hopeless at keeping regular contact. His family do WhatsApp me for a chat or a catch up as we live in different countries.

DS phones his dad more than he phones me, but it’s usually a football related conversation with sundry family news tacked on. Once they have finished talking about football, he will often put speakerphone on if I am around, but we do exchange WhatsApp messages and he sends jokes and photos of his latest carving projects. DD does phone occasionally, and it is me, and not her dad, but is more likely to message. Even though she is tethered to iPhone and watch, she’s not brilliant at picking up messages so I use a family WhatsApp group because I know if she doesn’t pick up a message, SiL will.

Curlywhirly, mine know that I rarely answer the phone. Their dad died when they were young so that situation of who they talk to didn't arise.

They tend to text or email sometime during the week - just to check that I'm not dead (family joke) then we do a Sunday morning Zoom session. I know they contact each other to check who's heard from me.

I was shocked to discover that my friend's husband reads her emails and texts, though. I'd hate that!

Our boys ring their dad if they have a financial/work/DIY problem; they ring me for all other problems! But they do also ring to see how we are if we haven't spoken for a couple of days. And how the tables have turned - if for some reason we don't answer the phone (landline or mobile) when they do eventually make contact we are grilled on where the hell we have been and why don't we answer the blummin' phone!

My AS tends to contact me and my AD tends to contact my DH. I wondered today wether they’d once had a conversation about sharing the burden of contact. ?. My DH and I share the info from them with each other. It keeps us talking ?

It's different but not preferential. My AC will come to me if they need support or to talk about a situation. I tend to get longer visits with them. My DH probably gets more frequent short visits at coffee shops because he works close to their workplaces and I don't. They contact me to organise visits with us both.

we do a variety of things. Ignore your friends comments

Same as Monica and we also do WhatsApp video calls. We have separate groups for each child with their partner, but also a family group chat.
My daughter tends to use the landline, but my sons use mobiles.

Same as Monica
And when our AC are actually here ( which seems to be most of the time as they live locally) they chat equally to both of us about all sorts of subjects.

When AC ring they chat with who ever answers the phone and when that chat is over the phone is passed to the other parent to have their chat. News gets given to both but when speaking to me the phone call is more likely to wander onto other subjects .

I would say yes, the same. However for different reasons in away. Me, arranging grand children care, maybe getting things, food at a particular shop, sometimes clothing. Husband, helping with jobs in their homes, taxi service borrowing tools and garden stuff. We each have 'our place'.
