Just to give you an idea of time frames, it took us 3.5 years to adopt DD1, we are now in the process for DD2 just over 2 years and expect to be another 9 months or so before we bring her home. I know of others in the process alot longer.
In saying that, waiting times for prep courses have come down depending where you are in the country. Inter country adoption is in a difficult time at the moment ie not many countries available to Ireland. Hopefully that would change when you'd have to pick a country. ( we had different countries in mind, but did'nt adopt from the first, ICA changes all the time, countries open and close )
Since we ratified Hague, just over a year ago, you now have to adopt from a Hague ratified country. This tends to make the children older, ie over 12 months although I do know of someone referred a 3 month old girl from India recently. ( you young age will be an advantage to ye )
We will ( when home next year ) have adopted 2 daughters, Vietnam, we would have had a choice but with India, it was always going to be a girl.
Costs ?????? do vary depending on where you go, some have very little fees, others have larger fees, and of course you have to travel. If you PM me a specific country, I could give you and idea.
Do contact your local HSE straight away, to get yourselves onto the waiting list for an information meeting, and take it from there............ it's a roller-coaster ride, up's and down's, lots of paperwork, but there will always be someone who will have been there done that who can help
and it's sooooooo worth it in the end
Best of luck.
