I was gonna say... why would you need to be 25 to get working ta credit!! I am planning on getting a job once baby is about 9 months or so.. i will be claiming it.. if i cant i wont be able to go back to work! The jobcentre etc are pretty helpfull for getting people back into work.
You will be fine finacially, you have maternity pay and your lucky. I will be living purely off child benefit, income support, and ill have to claim housing benefit and council tax benefit, I need to find a flat soon as, but i litterally cant pay any extra above the benefit so im limited to find a flat where the rent comes to as much as the housing beenfit. And i got screwed over for mat pay etc, so your really lucky to have that, you will be fine honestly, x
