5 mistakes I made when I had my second child, and how to avoid them

Adding a kid to the family adds a lot of expenses; that much we already knew having done it once before. But as our son was four by the time his sister came along, we had long adjusted to the expenses associated with his clothing, food, art supplies and toys, summer camp, and tuition.

Along with the large but one-time costs of the birth itself, having a baby adds in all sorts of costs, from diapers, wipes, and creams to clothing regularly outgrown and replaced and, soon enough, to food. While all reasonably predictable, I didn't take the time to think through our family's new projected monthly expenses and make sure we were still within a good budget.

Now in preschool, our son Ben is as energetic and active as any kid his age. But as a baby, he was much less physical than many children and he seldom put himself in risky situations. He rarely if ever crawled onto things from which he could fall off and didn't tend to grab for objects on shelves or tables. He didn't try to play with cords or outlets and he almost never put non-food items in his mouth.

Scarlett, on the other hand, was born with a mandate to crawl up (or down) the stairs, she tries to get on top of every piece of furniture, and everything smaller than a shoebox goes straight for her mouth. Safely parenting her means a level of attention in the moment and foresight in how we baby proof a room that is nothing like we experienced the first time, and it simply never occurred to me how different this entirely individual child would be.

With a preschooler and a baby, just getting out the door to go to a park, museum, or a store can feel like an expedition. The good news is that my wife tends to be fully prepared in terms of diapering supplies, spare clothes, a snack for our older kid, and so forth.

The bad news is that often enough that much needed diaper change occurs just as the preschooler finally got his shoes and coat on, and by the time the baby is good to go, he needs a potty break or a snack. Mealtimes, bedtimes, outings — everything in life now takes markedly more time than it used to, and in a cruel twist of fate, the world has refused to add more hours to the day.

As a parent with two children, I look at families with three or more children with awe; I don't know how the parents do it. But what many parents with multiple kids tell me is that the switch from one to two is far more dramatic than from two to three, three to four, and so on. When we had our son, my wife and I could tag in and out as needed and give all of our attention to him when spending time as a family.

When our daughter arrived, it meant almost no "adult time" save for an hour or two before bed, by which time we were both exhausted, and few opportunities to give either child full attention. These days, we're more fatigued, we get less done, and we're often stressed. But on the other hand, our son is now learning Mandarin and our daughter has mastered saying "mama" and "dada" and she's working on saying "Ben." In the bigger picture, a bigger family is more tiring, but it's also a great thing.
