Start With the Numbers, Not the Nursery

It is tempting to begin with prams and paint charts, but the most useful first step is a plain sheet of paper with two columns: what is coming in, and what is going out. Babies do not arrive with a price tag, but the first year usually costs somewhere between £5,000 and £8,000 for most households, and that is before any loss of earnings is factored in.

Before you buy anything, spend a month or two tracking your actual spending rather than your assumed spending. Most people find £100 to £250 a month of quiet leakage — subscriptions, takeaways, an unused gym membership. Redirecting that now does two things: it builds a habit, and it creates the beginnings of a buffer before your income drops.

Work Out What Maternity Pay Will Actually Be

This is the calculation that catches most first-time parents out. Statutory Maternity Pay (SMP) is paid for up to 39 weeks. The first six weeks are paid at 90% of your average weekly earnings with no upper cap, then the remaining 33 weeks are paid at £187.18 a week or 90% of your earnings, whichever is lower.

To qualify you generally need to have been employed continuously for at least 26 weeks by the 15th week before your due date, and to be earning at least the Lower Earnings Limit. You must give your employer notice and provide your MATB1 form, which your midwife or GP issues. If you are self-employed, changed jobs, or do not qualify for SMP, Maternity Allowance may be available at a similar rate.

• Check whether your employer offers enhanced maternity pay on top of the statutory minimum — many do, but the rules around repayment if you do not return are worth reading carefully.
• Ask about Shared Parental Leave if your partner earns less than you do; in some households it makes financial sense for them to take more of the leave.
• Statutory paternity pay is available to the partner for up to two weeks at £187.18 a week or 90% of earnings, whichever is lower.

Once you have a monthly figure, model the household budget on that lower number for the full leave period. If it does not balance, you have months to adjust rather than weeks.

Plan the One-Off Costs Before You Buy Anything

The set-up costs cluster into a handful of big items. A travel system or pram can run from £300 to over £1,000. A cot and mattress add £200 to £600. A car seat is £100 to £300. Then come the nursery furniture, monitor, steriliser, sling, and the endless small purchases that somehow add up to several hundred pounds.

Two safety rules are worth holding firm on. Buy a car seat new unless you can be certain of its history — a seat that has been in even a minor collision may no longer protect your baby. Buy the cot mattress new as well, since a used mattress may not meet current safety standards and can carry a higher risk of sudden infant death syndrome.

Everything else is negotiable. Cots, Moses baskets, baby baths, bouncers and clothing are all widely available second-hand in excellent condition.

Where You Can Genuinely Save on Baby Essentials

Ongoing costs are where the real savings live, because they repeat every month.

• Nappies: disposables typically cost £25 to £40 a month. Reusable nappies need £200 to £400 upfront but often pay for themselves within a year, especially if you plan more than one child.
• Clothing: babies outgrow sizes in weeks. Buy bundles second-hand, accept hand-me-downs, and resist buying ahead in bulk for a season that may not fit.
• Feeding: breastfeeding is free but a pump and bottles cost money. Formula feeding runs roughly £50 to £70 a month. Either way, do not over-invest in equipment before you know what works for you.
• Local networks: nearly-new sales, community noticeboards and parent groups are where the best value is found. Borrow rather than buy wherever you can.

Build a Cushion and Check What You Are Entitled To

Aim for a buffer that covers three months of essential outgoings, or a realistic £1,000 to £2,000 if that feels out of reach right now. This is not an emergency fund in the abstract — it is the money that stops a broken boiler becoming a crisis in month four of maternity leave.

Then check your entitlements, because many families miss them:

• Child Benefit pays £26.05 a week for your first child and £17.25 for each additional child. Watch the High Income Child Benefit Charge if either parent earns above £60,000.
• Tax-Free Childcare tops up childcare costs by 20%, worth up to £2,000 per child per year. Universal Credit claimants can instead get up to 85% of childcare costs covered.
• Sure Start Maternity Grant offers a one-off £500 payment in some parts of the UK if you receive certain benefits and this is your first child. Scotland has its own equivalent.
• Funded childcare hours are now available from nine months for eligible working parents, which can substantially change your return-to-work sums.

Protect the Plan Once Baby Arrives

Two administrative jobs are easy to postpone and important not to. First, make a will and name a guardian. If neither parent has one, the decision is left to the courts. Second, check your life cover and any death-in-service benefit through your employer — many parents are underinsured without realising it.

Finally, diarise a review for three months after the birth. Actual costs rarely match estimates, and a short, honest look at real figures will tell you whether to adjust, return to work earlier, or simply relax knowing the plan is holding. Financial preparation for a baby is not about predicting everything perfectly. It is about making the surprises smaller.
