Sippy cups are not a developmental stage

At a baby’s six month old check-up I advise parents to have their child start drinking from a cup.

Some respond with surprise,” A cup? So young? How exciting! Do you mean a sippy cup?”

“No,” I explain. “A regular, open face cup.”

Then I get incredulous looks. “But how will our baby manage that?”

Just like your baby “learns” how to eat food off a spoon, she will have to practice. You will have to help her at first. Just put water in the cup. Who cares if water spills? You see how by this age she naturally puts her hands together and pulls most things to her mouth. With practice, she will learn to drink out of a cup. Just like everyone else did before sippy cups were invented.

“But when,” parents ask me, “should we introduce the sippy cup?”

The reality is, sippy cups satisfy a parent’s desire to be neat and to avoid mess. Sippy cups are not a developmental stage. Did I use sippy cups with my own kids? Yes I did, especially with my twins, because anything I could do to decrease mess in my home I welcomed with open arms. But it is perfectly okay to never introduce sippy cups to your child.

Because sippy cups are spill-proof,  it is tempting to leave one out all day for your child. If the cup contains water, this practice is safe. However, many toddlers have ended up with a mouth full of cavities in their brand new baby teeth after sipping milk or juice all day long out of sippy cups. Constant sweet substances on the gums can sink in and affect baby teeth. Just as we advise parents of bottle fed babies to avoid allowing the child graze from the bottle all day and to avoid falling asleep drinking a bottle, young children should not be drinking sugar-containing drinks, including milk, all day from a sippy cup.

“But I only give my kids water mixed with a tiny bit of juice in the sippy cups,” I hear parents say. Yes, kids (and grownups) need water, but watered down juice is not the same as plain water. Watered down juice is sugar water, and it harms teeth just like straight-up juice. In addition, drinking watered down juice teaches kids that all beverages need to be sweet. Sweet drinks do not actually quench thirst; rather, they make kids feel thirstier. Remember that unlike adults, babies and toddlers have not formed unhealthy habits yet, so teach them that water and milk are for drinking. The only exceptions are electrolyte solutions that are used to prevent dehydration during vomiting and juice once a day (prune, pear, or apple) for constipated children. For nutrition, fruit is much healthier than fruit juice.

So put water in the open faced cup and allow your baby to imitate you and drink out of it. Then, around your child’s first birthday when most parents wean their children from breast milk or formula to cow milk, put the “big boy milk” or “big girl milk” into a cup.  Aim for all open cups by at least two years of age. If you decide to use sippy cups, as I did, for neatness sake, do not forget practice with a regular cup. Get rid of the sippy cup whenever you are tired of washing those moldy valves and tired of rescuing them from your drain or garbage disposal.  You might have a “sippy cups are for car rides” policy and use open cups at home.

What about straw cups? Well, think of it this way. Do you plan to travel around with straws in case your child becomes thirsty? Sure it’s fine to teach your child to drink out of straw. It’s healthier than a sippy cup because most of the milk will bypass most of the teeth. But again, it is easiest in the long run to teach your child to drink out of a regular cup so that in any situation you know you can offer your child a drink.

All kids are messy. The younger you practice with your child, the sooner she will be drinking out of a regular cup like a pro. Just in time for finger feeding which means self-feeding—more mealtime mess!

    I was told by a speech therapist that Sippy cups and/or thumb sucking/pacifiers can cause difficulty with articulation and clarity of speech in some children. Also a lisps, are another common issue.
    I have two kids in speech therapy that used a pacifier and sippy cup way too long. My older two kids had the pacifier taken away at 6 months old and really liked regular cups early on and don’t need speech therapy.
    See a theme:)

    This article reminds me of when my daughter was in a 2-year old tots program many years ago. When the parents came to a holiday party with the class, we were all surprised to find our little kiddos drinking quite confidently from little Dixie cups. “You mean, they can do that?” was the general reaction!

    Love your articles!!

    Okay I cannot wait to make my husband read this article. He is the type of person who will do anything to avoid a mess. I think our 2 year old is perfectly capable of drinking from a cup and we could save some money on all the sippy cups we go through! Thank you for also pointing out that children do not need juice! My husband thinks it’s torture to make her drink only milk or water.

    “Do you plan to travel around with straws in case your child becomes thirsty?” Actually, I do and it is quite easy to put a pack of straws in the tote bag and not even think about it for months…after all, I need to carry her Bjorn toilet adapter with me everywhere (since my child was potty-trained easily, day and night only underwear no pull-ups, at 25 months of age)…it’s not like parents don’t have to carry a ton of things with them anyway. And, unlike drinking out of a regular cup, she has never scared me by looking like she’s choking when she drinks from a straw. And she has beautiful, healthy teeth (no juice ever…she prefers water & milk). (Uses straws, not sippy cups). There seems to be such a rush these days to get kids to do everything faster, including drinking out of regular cups in toddler classes. Straws are available almost everywhere, in all stores/restaurants and as long as she masters drinking from cups by the time she is in kindergarten, so be it, why risk her choking.
