He’s being ridiculous right?? What should I do

I’m so annoyed at my bf. He’s being ridiculous, right?

Our 7-month-old was supposed to get shots a couple of weeks ago but I wasn’t able to take her because something came up and I rescheduled the appointment. They sent a letter in the mail the following week stating if I canceled 2 more appointments that they would not continue to see her as a patient so I’m not trying to cancel any more appointments. Well I’m currently pregnant again and have an ultrasound appointment and bloodwork scheduled the day she’s supposed to get shots, our appointments are 45 minutes apart and our doctor's locations are on the opposite sides of town so there’s no way I can make it to her appointment and mine.

I planned on taking her with me then going straight to her doctor when I was done until I realized how close the appointment times were, so I asked my bf (her dad) if he would just watch her while I go to the doctor and him take her to her appointment that way I don’t have to cancel hers again since it’s already been put off and I can’t miss my appointment because I’ve already been waiting a month for this ultrasound and my doctor said that was the soonest they could get me in. They have a rule that they have to see you before you’re 12 weeks otherwise they won’t accept you as a patient so I can’t cancel my appointment either because they won’t be able to get me in again before 12 weeks since they’re so full.

I don’t want to switch doctors because I’m high risk like I was with my last pregnancy so they know my history and I would like to stay with them. He said no he’s not taking our daughter to her appointment because he “doesn’t know how” and told me to either cancel my appointment or cancel her appointment. I explained to him why I can’t do that and he still said he is NOT taking her because he’s not “comfortable” doing it by himself and told me to ask one of my family members to take her?! So he would rather someone in my family take HIS daughter to the doctor.

I don’t even know if her doctor would allow that as I didn’t put any other family members on her paperwork. Idk what to do bc there’s no way I can make it to both appointments and I shouldn’t have to cancel one when he literally has nothing to do that day and can literally take her as her dad he just doesn’t want to. I got mad obviously because I was already stressed about 2 appointments on the same day and he’s not even trying to help so it’s all on me to figure it out now. He told me I was being ridiculous and it’s “not a big deal” to just cancel one and that I was being dramatic.

What should I do? He said he shouldn’t be forced to take her to the doctor if he’s not comfortable with it.
