Very interesting to read that people have very different view points r.e this.
We both work full time, mainly from home, have no childcare costs as we both juggle our hours/shifts between us to allow us to save on childcare (certainly not judging people who do use their child benefit to help with childcare costs) and I often do work at night when DC is in bed.
My DC doesn't miss out on anything. My DC has been given opportunities to go to various classes/clubs however is not keen on this - might change the savings aspects when this does happen. We often do days out that are cheap or for an occasion because I don't want my DC to expect this all the time, we go swimming weekly that costs a grand total of £1.50.
My DC has mainly hand me down clothes from other family members that have absolutely nothing wrong with them or have been bought in the sale, I'd rather this than buying new every time as I absolutely hate waste and its cost effective. We do however always buy shoes new but certainly not expensive, always from Asda or similar.
In relation to the family pot for food shop we managed to afford food (Aldi and Lidl shopper and certainly nothing special or fancy) before DC came along so it's just continued this way however again this might be a different story if we had to buy new clothes all the time for DC or circumstances change in some way. We also don't smoke or drink, I'm sure there are plenty of people that stick a bottle of wine/beer in with their food shop that comes out the "family pot", no judging at all but it's very much swings and roundabouts.
So as I've tried to portray in this info I do what works best for our family and totally understand everyone's situation is different in various aspects and as things change we will change it accordingly if needed.
**Also someone has said £140 a month? Is this for more than 1 child because we definitely don't get that.
