Your child's looks and personality will be different depending on whom you marry. While I'm keeping the description of each child in his own page, there is some basic information about them that applies to all three children.
The Toddler Stage (chapter 2)
Toys: You start off with just a coloring book, but can also buy a ball, blocks, and a toy car from Van. They're not that expensive; they're under 500G each.
Interaction: Often, when you talk to your child, he'll ask you to pick him up. Do so with the Y button. Once you're holding him, there are 4 things you can do:
|Talk: A button. He'll tell you want he wants you to do, or... he'll let you know how he's feeling in interesting little ways. (Like, how exactly would you pronounce what Nami's child is saying in the screen to the left?)|
|Pat on back: X button. He generally doesn't ask for this often, but doesn't seem to mind it if you do it anyway.|
|Toss: Press up on the Control Stick to toss the child into the air a bit. Muffy's child loves this one most of all.|
|Snuggle: Press the Y button. Nami's child loves this one most of all.|
In addition to playing with him, you can also give him a bath on certain days. These days vary each month. To see if you can bathe him, just enter the kitchen at a time when he's there (around 6PM seems to be the best time.)
The toddler stage is the only stage in his life in which you can pick him up and take him places, so take advantage of that to develop his interests! His interests may change in later chapters depending on where you take him as a toddler.
Genetic Strengths and Interests: Depending on who you married, your child has a set number of strengths and interests. The first set (strengths) is purely genetical; it's simply what he's naturally good at. The second set (interests) are simply what he likes. Though at first your child has a default number of interests, these are the things you can actually influence. Your actions, what friends you make and where you take him can and will change his interests.
To develop his interests in...
» Keep him around the farm most of the time
» Keep your animals out in the pasture as much as possible
» Show your child animals
» Snuggle your animals
» Use the Milking Room
» Milk your cows/goat by hand as opposed to using the Milker
» Take him to Vesta's farm
» Buy and use Fertilizer
» Show your son seeds, crops and trees
» Grow things as much as possible
» Take him to Gustafa's hut and the mansion
