Hi I’ve read most of your posts and I remember how tough it was when returning from maternity with the second child.
Two children with expensive childcare (probably cost the same as around 80% of my PT wage!) . I knew the situation was temporary so it was endured until at least one had 30 hours childcare - the free hours helped but it was still expensive with the 30 hours.
However my choices were to either carry on working to pay for childcare (the 80% income to childcare costs lasted approx 6 months) or quit my job and restart my career (from the bottom) when they are older - the disadvantages would be bringing them up in a single income family for the foreseeable future (poorer for the long term rather than 6 months) and when I do restart my career, I would have lost any competitive edge to my skills gained over the past decade. Therefore restart my career at a much later date, on a lower starting salary
During this really difficult period (until they both started school nursery at 4 years old), I made a decision to only save £10 a month each - sometimes none - and only put in the money they were gifted at Christmas and Birthdays. They were still getting hundreds for each birthday/Christmas so I didn’t feel the need to save as much from my wages
From your posts, you had already saved £100 (with your own wages) in December into their accounts . Due to the increased costs in December, if i were you, I wouldn’t have saved £100 this month.
if you decided not to save £100 for them this month, at least they had a £100 gift from PIL.
so technically you wouldn’t be taking money from the children, you just didn’t save any money from your wages.
i saved £10 per month for each child until they were both in school - so at least 2 years of minimal savings into a regular saver (which paid a better interest rate). Once I had more disposable income, it went up to £100 per child per month plus all their gifted money. I have a few months (joint income) saved. Got rid of all the debt accrued on SMP (who can realistically live on £136 a week with a baby and a 3 year old ?!)
sorry not to gloat, but letting you know it will be much easier later on and to only save what you can for now as you’ll be able to catch up with the savings when they’re at school.
Good luck but if you do take the money, see it as the money you saved into their account earlier this month rather than the gifted money. The true decision is whether or not you can or can’t save the usual £100 this month or next
