@Boreded - I actually made decisions for my DC when they were small.
For example, I started their pensions when they were 10 and 12. Which means that DD (22) has the same pension projection at 60 as I do (I pay a lot more into my pension - more than 10x the amount I put into hers). Compounding is amazing - make the most of it!
Prior to that I set up S&S child trust funds. They transferred these into ISAs when they reached 18.
My advice would be:
Do not drop to PT. I know childcare is expensive, but having a career and keeping up with your pension contributions is really important. Plus there are so many more flexible working options nowadays.
Increase the amount you save when you get a payrise. You don’t miss money you’re not used to spending. So save it rather than adapting your lifestyle to your new salary.
Tracker funds are a great way to start investing. You don’t need to know much. You can just pick a fund that tracks the FTSE or whatever.
Don't bother with bonds/gilts. They’re supposed to be low risk, but my experience is that they’re not really (and tracker funds tend to outperform them by some way).
Put the money for your annual tax return in Premium Bonds. It’s not really your money, so you have to save it somewhere - and it’s fun to see if you’ve won each month.
Invest rather than overpaying your mortgage. This seems counterintuitive. But over 25/30 years the compounding effect of investing is likely to beat the amount of interest you save by some margin.
Understand tax. Know what is taxed and what isn’t. Monitor the latest policy changes. Think about salary sacrifice if you’re close to a cliff edge.
Plan for retirement. Pensions are a really tax-efficient way to save. But the money buoy receive from a pension is taxed as income. ISA savings are made after you’ve been taxed, but the money isn’t when you access it. A balance of both gives you flexibility.
Tall to your children about money. Because they need to learn. Being coy isn’t going to help them.
