How can we persuade ds that he does, in fact, have TWO parents?

Ds has never let dh settle him, not since he was about 8wks old. (Okay, not never, but as good as.) Dh baths him every night (lately there is screaming unless I'm in there too), plays with him, reads stories, helps feed him dinner, helps dress/change him evenings and weekends. He is genuinely besotted with ds and shows him much love and affection (and much more fun than I am!). Ds also sleeps between us most nights.

But if we leave ds with dh and I disappear, ds always ends up sobbing, sooner rather than later. When I was working 1 afternoon/week ds would scream most of the 4hrs I was away. And if ds wakes, he will cry harder if dh goes to settle him.

Demoralising for dh, exhausting for me. Is there anything we can do about this?

my dd was like this would not settle for anyone else until this summer at 14 months when she stayed with her dad for the first time over night (we split when she was younger). i was worse than she was.
i think its a phase that wil pass, as others have said 10 months is seperation anxiety time, i'd be inclined to ride it out and just get dh to help as much as possible. babies need a primay carer to feel secure and attached, this is what your bab is checking out
