Starting over: My 4th hubby's 1st

Rachael
Has anyone else entered into a new relationship with kids and their partner doesn't have any yet? My husband is great with my kids especially given the fact that he's never been around them (kids in general I mean) haha! 
We just found out yesterday we're expecting our first together and he is beyond thrilled! I just want this pregnancy experience to be enjoyable together with him. I'm just afraid that with this being my 4th and obviously not a "new" experience for me and that I may take away from all these firsts that are about to start for him. I'm just wondering if I should refrain myself from sharing some of my knowledge through my own experience (through pregnancy, birthing and the first year after...etc) or if I should let him just look everything up and research things as he he does with everything else... lol 😂
