Start budgeting now, I worked through all our bills and income
Then from that a goal of what we could save, and literally saved saved saved ( I admit I was lucky to have the capacity though that was because husband earnt more he is an awesome worker and pays his bills but terrible At saving so we got a joint savings account to Poole both our resources
Do you get full pay for any of the first part of your job? As I pay about £300 pm out in travel costs for work so first two months I saved that in addition.
I looked into free baby clubs locally when he was little, and got a lot of clothes second hand on Facebook for sale sights ( they go through clothes so quick that the second hand clothes were good as new but was getting a whole wardrobe for close to £10 a go. Same for toys ( he is now 13 months ) for £10 once I got about £150
Worth of toys .. just kept an eye on the for sale sight brought stuff not as and when needed but when a good deal
With the right bits came along for future use.
Using Aldi nappies to make savings stretch.( used pamper sand both to the same effect )
Don’t forget milk .. your plan may be to breast feed but it may fail ... I hadn’t budgeted for that so that hurt.
End of Mat leave I did have paid holiday to take and the bank holidays I was paid for also. Not sure I’m your works policy but that gave me a month and a half of paid
Holiday at the other end of my maternity leave with an income.
I did get a yearly pass to a local zoo when son was 6 months ( also has soft play etc) that was invaluable as although I paid £44 I literally went every week it gave us fresh air ( always packed a picnic / bottles so
Didn’t buy anything ) and the soft play helped him socialise and run off steam.
You can get lovely second hand snuz pods etc too just buy a new mattress and you will save £100 easily .. which buys more time
I homemade weaning food ... just buy some freezable pots already had a hand blender ( you can buy baby food blenders but I think it’s not needed if you have a blender )
