seconding what windfalls has said
Very few people have neither mortgage nor rent. I’m a single mum, I did have a great adoption package from work, but little in the way of savings. My son was at school after 6 weeks, I had 13 months off. 9 years on I’m still part time but slowly nudging towards full time. You manage.
Remember that even if you adopt a school age child, there are 13 weeks of school holidays to cover, plus teacher training days, snow days etc. Personally I feel if you have a school age child, its important that in that first year they don’t go to holiday clubs etc. Its important time to build your relationship. I used no childcare, after school or holiday clubs at all the first year, apart from one week which was basically an extension of the school term for a week. I really feel this was critical to consolidating our relationship.
Adoption will be an enormous shock to you. Believe me, I needed every last day of my 13 months and wish that I could have had another 6. You will be more exhausted, physically, mentally, emotionally than you can imagine. Until you get your adoption order you will have visits from social workers and review meetings.
Few people have no issues to address when they go through the process. Think of this as the first problem to solve. What can you do to make the finances work, savings, reducing expenditure, remortgaging can save significant amounts of money. When I first started looking at adoption my finances did not stack up, so I got a new job, took me two years to find the right job but it was worth it to put me in the best financial position, Don’t forget there is now the option of sharing the adoption leave.
Finally remember that like football, adoption is a game of two halves, getting approved is one thing, getting matched is another. There will be plenty of people who can offer 12 months, if you can’t, its potentially something that can tip the balance away from
