Arthritis, does not just go away or get "cured."
And it is debilitating.
I have relatives with Arthritis.
Can you alone, handle 2 kids, in all aspects?
Because, due to your Husband's health, you cannot expect him... to do the normal things a Husband/Dad, does, daily.
And his health, is not predictable.
I have 2 kids that are 4 years apart. And for me/us, the age spread is great. My eldest is a girl. My youngest is a boy. And their age difference has worked out very well. Because, by the time I had my 2nd child... my eldest was almost 4. And she was old enough then to be out of diapers, she was going to Preschool and was developmentally at a more able and independent age. So having another baby, at that time, was nice. And my kids are very close and get along.
I had kids late in age. And fortunately, we were able to get pregnant naturally without fertility help etc.
And fortunately, even with my late maternal age with each of my pregnancies... my pregnancies were normal and my kids were born healthy. But I did have the Amniocentesis tests, with both of them.
Because, when being pregnant after age 35... other factors can come into play.
You need to consider everything.
Do you have family in your same town who can help out?
What about costs for Preschool etc. or Daycare?
Can you handle those aspects of a child and their needs and developmental stages and costs?
Yes, being the main caregiver/parent for 2 children will be harder.
Can you do that?
And go through all the baby stages, again?
And the costs of it?
Then, you'd have to speak to your OB/GYN, if you want to get pregnant again and get a check up etc.
Then, the timeline for conceiving is not always as fast, as we would like it to be.
Many things to think of.
And how that will also impact your quality of life and your family and marriage.
Does your Husband have Disability insurance?
How does he, have a "regular" income if he is working and cannot go to work, due to his chronic arthritis pain etc.?
I don't know of any Employer, that would keep on an employee like that, who cannot be at work due to health problems etc.
Then, he probably needs to see other Doctors, and explore if there are better ways of handling his Arthritis and pain management... since his current status is that he is often resting at home and exhausted and cannot do anything, etc.
So, he has to re-evaluate his health treatments too, etc. and take the initiative to see if there are better ways of treating his conditions etc.
And you will need to pay for Daycare or childcare for both your children... being your Husband cannot care for the children and a baby.
