Can I do it alone?

I have a son. He’ll be four in a few weeks – a sweet, smart, active little boy with a big heart. However, his father and I split up over a year ago, largely because I wanted more kids. While we had agreed upon it previously, he later decided that one was enough. He loves our son, of that I have no doubt, but he refused to have another child.

I’d had enough.

The breakup was nasty but I agreed to shared custody. Leaving was the hardest thing I have ever done – not leaving him, but sleeping under a different roof than my son. However, our custody arrangement is such that I see my son pretty much every day, and most nights. At least it’s bearable.

My son keeps asking me to bring home a baby for him (which is just so darn cute), but I wish it were that simple. I want another child. My biological clock is ticking louder every day. In a few months I turn 40. Somehow that number has always seemed the age I should be finished having kids.

For the past nine months (irony, anyone?), I’ve been actively searching for Mr. Right. Someone intelligent, attractive, single, honest, interesting, gentle, kind and creative, who likes kids and wants to settle down – and who hasn’t had a vasectomy. There isn’t anyone like that in my regular life so I’ve tried four different internet dating sites. So far I’ve met 18 local men and, well, short version: no luck.

So I have a choice.

I can take the risk and wait, or I can cut out the middleman (pun intended) and just do it myself with the help of a local fertility clinic.

I can afford the procedures and they’ve accepted me as a client. I’m lucky to have a job that will pay me almost my full salary for a full year of maternity leave, and a great health plan that covers most costs. I make enough money to be able to support another child. What more do I need, right? Case closed! Decision made! Sign me up and show me the stirrups!

Then the doubts set in.

If I get pregnant this fall, my son would be five by the time the baby was born. Is it fair to him? Will I have the energy to do all the things he needs me to do for him? Will I be able to get him to school on time – help him with his homework? Will he resent sharing his bedroom? Will he resent sharing me? Will his father think that he can steal our son away from me because I have another child? I wouldn’t put it past him.

Is it fair to deprive a child from knowing his father? Will the baby wonder? Will this baby resent that my firstborn son gets to spend time with his father but he or she can’t?

I remember those first months (and first years) of having a baby. It’s exhausting. Not enough sleep, constantly on call, never a moment of privacy – and that’s what it was like when the father was there to help out.

What happens if I’m on my own? No one is going to make me a sandwich. No one is going to vacuum for me or unload the dishwasher. No one will change a diaper once in a while to give me a break. No will bounce a teething infant for an hour or two in the middle of the night so I can sleep. No one will pick up groceries from time to time.

I will have no one to rely on but myself.

I don’t have family around, and all of my friends are leaving town one by one – it’s their careers, I always knew they’d be going sometime. Could I hire a doula for the first few months? A nanny? How much would that cost? Can I afford it? How do I find one? Would she expect to live here in my tiny house? Where would I put her?

What would it really mean to have a child on my own? Can I do it alone? The only single moms I know had a hell of a time, and they had friends and family around to help. What if I have twins? How the hell would I handle that on my own? My mother was a twin.

Am I strong enough to handle it?

Donor insemination.

It’s the right thing to do.

Right? Tell me I’m right.

Please.
