Hi. We struggled due to childcare cost but then we decided sod it, we'll find a way. With me staying at home the tax credits were adjusted & we actually work out exactly the same as we did before. Having said that my old job was on rubbish pay. We had Mia then tried again after 9 months & was lucky to get pregnant straight away. Since Ava arrived I'm a ful-time mum & part-time student & Lee has changed jobs to have better hours.
I know what you mean with worrying about random things. I bought 5 litres of washing up liquid & things like that in case I had to stay in hospital for ages as Lee can't drive. Things have a way of working out. I worried Mia would feel pushed out with having another but it actually seems easier now there are 2 of them.
I hope you are able to go with whatever you decide. Good luck & happy new year. X
