We already had drawers that we put the changing mat on.
I don’t think we bought any toys as we were given so many!
Factor in a higher food bill, breastfeeding makes you hungry,
I didn’t want baby on foam so bought natural wool/coconut mattresses that were more expensive than basic ones.
Baby clothes wise, DS grew very quickly so went through about 6 different clothe sizes in the first year. I bought most of it in bundles from eBay, probably about £25 each time, one size I bought new and it was over £60 and didn’t do that again!
As above DS was huge so he grew out of the infant car seat before he was 1, the next size up was probably close to £200.
We also bought a stokke tripp trapp high chair at around 6 months, They take up much less space than other high chairs but I think that was about £300.
I went back to work after 6 months and expressed milk for the next 6 months. Breast pump was £200 ish and glass bottles were probably about £80 in total. I only needed these because of when I went back to work.
First time round we used about 8k of savings to cover mat leave but at the time my DH was only earning about £15k pa (phd grant) and I was usually the main earner by a very wide margin. Second time round (DH has finished the phd) we’ll only use about 2k of savings and if we do that’ll be for a holiday or something.
