There's nothing like welcoming a new addition to our families - from their tiny fingers and toes to those quiet moments where we imagine what kind of person they will grow up to be.
In the meantime, though, we have to deal with the associated financial costs of expanding our families.
And while we by no means enjoy budgeting, it is important to know how much we'll need to shell out in order to have that extra room for the baby or more food for our ever-hungrier brood.
A new study has found that a one-bedroom house starts at about £168,000 to purchase, and each extra bedroom increases the price of the home by about £104,400.
The research, conducted by MoneySupermarket, also showed that the weekly shop for a family-of-three costs an average of £42.70.
For a family of five people, though, a trip to the shop will end up costing them £53.70.
That adds up those families spending an average of £572 more each year on groceries than families with just three people.
Another important part of growing your family? Getting a car to fit them all!
Whether you need to give your little ones a lift to football practice, or you're planning a road trip, a vehicle with plenty of space for your family is key - but it can prove pricey.
If you're upgrading from a five-seater car to a seven-seater car, those larger vehicles can cost over £10,000 more than their smaller counterparts.
The research found that cars that accommodate families of five to six people cost an average of £30,000, while cars for families of one to four people are just £15,000.
And then we have to consider the utility bills (groan).
The combined yearly cost of water, gas, and electricity bills go up by £125 if you're growing from a family of three people to a family of four.
But is anything more worth it than our kids?
