Absolutely! And I'm not planning on completely disappearing from bnb either so I'm happy to answer any questions you may have!
We were like you said - we didn't put a number on the IUIs either. I think that would make them too stressful! We had thought about this for a long time, but decided against it for several reasons. Then, one day, we just knew it was time. We were a few days before an insemination when I called to sign us up for the next informational meeting. At first we were planning to continue trying monthly while we were going through the licensing process.. but, again, decided that wasn't going to be the plan. I think it's best to make these decisions as they come. Only you will know when something is or isn't right!
It's definitely already been an emotional process. Sometimes it's incredibly happy and exciting.. other times it's completely terrifying and pretty sad. This is a road to becoming a parent but it's also letting go (at least in part) of this dream of pregnancy. And of having an infant in your home who you know from the start will forever be part of your family. That can be tough. But, even through the sadness I know this is the right path for us. I'm picking out a crib right as we speak!
You have a bunch of interviews, yes. But they're not deciding whether you're "good enough" to be a mom. And families come in all sizes and types of housing! You do have to have certain things.. like a room for a child, but it's more just a process to make sure your home is safe. Like I said, we have to pass a fire inspection.. but even if you "fail" it, as long as it's not something dangerous you can just agree to fix it as soon as possible. For example - we were replacing our deck over the summer and didn't get around to putting the railings up yet. That will make us "fail" our inspection. But, as it's winter and we live in Maine that's not something we can fix right now so it will just be marked that we will put deck railings up by June (or whatever) and that should be enough to "pass".
We also had to put down three references who had to fill out a questionairre about us. We were finger printed to pass all the logical criminal and background tests. Pretty basic stuff. We have a training to attend at the end of January to cover all the details of foster care. And the home study is basically just to get to know you and your family. Again, they just want to make sure you're in a stable place in your life so that you will be able to provide a safe home for a child.
It sounds daunting but so does ttc before you start! haha. Once you jump in you just take it one step at a time.. again - just like ttc.
Hopefully this isn't something you'll have to think about, but in the event that you do it's not as scary as it seems at first. I always joke that maybe we'll be placed with a foster baby and find out I'm pregnant all at the same time. haha.
When do you leave for vacay?
For me, I don't even know how I did it.. After my first failed IUI I completely crumbled. It was the lowest of the low from this whole process.. Possibly even lower than when I found out I was miscarrying. Anyway - after that, I kind of thickened my skin up a bit and the losses after that got.. not easier.. but less devastating, I guess? In any event, the only advice I can really give is to be kind to yourself. It's ok to be moody. It's ok to be angry. It's ok to be ok and happy and enjoy yourself too. This is a hard hard ride and you just do whatever it is you need to do to get through it. That said, be kind to your husband too. He'll have his bad days and you need to let him process as he needs to.
