Step1
Before you leave the house make sure your toddler is fed, well-rested, and in dry clothes or clean diaper. The main reasons why any child becomes difficult while out of the house is because he's hungry or tired. Grocery shopping is especially painful in this situation, so avoid it by solving the problem before it starts. Bring along your toddler's favorite snack and a drink as well, just in case.
Step2
Go shopping with plenty of time to spare. All too often as parents we get wrapped up in own tight schedules, and we simply rush from one place to another. If you relax and enjoy your shopping trip, then not only will your toddler relax as well, but you'll have far more patience with any behavioral snafus your toddler may toss at you.
Step3
Interact with your toddler. Nothing is very much fun when your companion isn't paying attention to you. Talk with your toddler and treat her like she's your shopping buddy...because she is!
Step4
Turn it into a learning experience. Toddlers love to learn. Start naming things you pass by in the store and explain what they are used for. Tell them about whether grandma might like Santa Clause to bring that to her, or that Auntie Susan has one just like that at her house. This helps a toddler create a sense of continuity in their world as well as develop an idea of what a store is used for.
Step5
Have a sense of humor. It's always heartwarming to see a mom or dad goofing off and having a good time with their child, so stop worrying about who will see you and go ahead and put on that silly hat and do a silly dance. It doesn't hurt anyone and you'll both get a kick out of it.
Step6
Say yes once in a while. If your toddler is always reaching out for things on the shelves, don't just swat them away, go ahead and let them have something. Obviously you'll want to give them things that they can't ruin like a stuffed animal, a piece of clothing, a roll of paper towels, or a plastic container--just use your parental logic. If they are occupied with one thing they won't have the hands to reach out for something else. Of course, believe it or not, this also avoids tantrums because your toddler doesn't feel like she's missing out on anything since she's been able to check things out for a while. Remember that a toddler's attention span is short--they will lose interest after a few minutes and you can simply put it back on the shelf without a care.
Step7
Keep your cool. If trouble arises and a tantrum boils, stay calm. Talk to your toddler quietly, and don't make a scene. Toddlers have sensitive egos, and they don't necessarily understand what they are doing, so making a scene can embarrass and confuse them. It's best to take your discipling home. Sing a song, gently soothe them. Give them a cherished stuffed animal or blanket. If this doesn't work, take them home.
Step8
Remember that any time can be quality time with your toddler. Forget the rest of the world and have a good time. If your toddler sees that you're having a good time then they will too.
