want my son there first

Veronica • George Alek Jr 4/08/17💙 Layla Jae 8/16/2018💜 Currently pregnant due in November

my son is almost 16 months. I was 1cm dilated at 34 weeks,tomorrow I go in for my 36 weeks appointment. They will be doing an ultrasound first,then I see my doctor. My son will be staying with my mom tomorrow and also when I do actually go into labor..that being said is it okay if I ask my sister and mom that even though I dont want him actually there when it happens,I do want my son there to see his sister right away before everyone else does..my husband requested this but the idea growing on me because family is going to want to take pictures with the baby but I want our son to be in the first set of pictures lol what yall think?
