Photoshoot with baby and baby daddy

So I want to do a photoshoot with my daughter and I for her 1st birthday . I’m do a whole collage full of pictures for her first year and this photoshoot will be like the big photoshoot I guess lol and I’m going to do something really cute with it for Memorabilia for when she gets older

I wanted it to be like a family photoshoot for her . But the only thing is my baby daddy and I are not together . He’s has another gf and we don’t get along but my ex and I get a long very well .

Him and I have talked about getting back together in the future but rn isn’t the right time we want to focus on ourselves and do what’s best for the baby rn .

Would it be weird if I asked him to be in the photoshoot with us , the last time we were in any pictures of all three of us was when we were in the hospital . I really want my daughter to have pictures of all three of us because my parent divorced when I was young and I only remember 2 pictures of everyone together and it always bothered me since i was little .

Should I ask him or would that be weird
