Which Sippy Cup Is Right For Your Baby?
Babies are recommended to start solids at around 6 months. When your baby start solid, you can also have her/him learn how to use a cup. The goal is to have a baby drink out of a cup instead of a bottle at 1 year. So the baby can go through a cup training. When she starts using the cup, she will most likely drop it a lot which will cause a spill. So sippy cup is used to minimize spill or leakage from the cup.
There are three types of sippy cups: a sippy cup with a spout, a sippy cup with a straw or a rimless cup. American Dental association suggests that a sippy cup with a spout should be used briefly, not for a long time. Long time use of a sippy cup can cause lisps in speech as well as a tooth decay. You can use a sippy cup as a transitional cup for temporary time and move onto a straw cup. You can also skip the sippy cup with a spout and start right from a straw cup if your baby is capable. However, some babies may find comfortable using a straw cup at 8-9 months. In order to fight speech problems, we recommend this cognitive verb toolkit secondary tool.
Sippy cups are also made of different materials: plastic, glass and stainless steel. Plastic cups are light so it’s perfect for a 6 month old baby. However, there is some concern with plastic materials leaching some chemicals over time. Although almost all plastic cups available in the market nowadays, say their cups are BPA free, plastic is a plastic. Glass or stainless steel on the other hand is a safe material. However, glass is heavier than plastic and it can break if dropped. If that happens, it could get dangerous for your baby so the glass cups are not listed here. Stainless steel is also heavier than the plastic and it could get dented if dropped hard on the floor. Glass and stainless steel cups are also usually more expensive than the plastic ones. However, they will give you a peace of mind that material is non-toxic and safe.
Start out with a light, easy to hold cup that is also easy on your baby’s gum. You may have to try a few different cups before you find the one that your baby like the best. You may have bought a stainless steel sippy cup for your baby but if your baby doesn’t like it at all for some reason, you may have to go with a different cup. If you do get plastic cups, check the number on the plastic cups for its plastic code. If you look at the plastic cup, you would find a number range from 1 to 7, indicating a type of the plastic. Your want to avoid number 3, 6 and 7. Number 3 is vinyl or polyvinyl chloride (PVC), 6 is polystyrene and 7 can be various plastics. Some plastics with the codes of 3 and 7 may contain Bisphenol-A (BPA). Vinyl, PVC and polystyrene are all known to be toxic to health.
Only small size sippy cups are listed below for a 6 month old baby to start. (5-7 ounce cups) As your baby grows bigger, you can get bigger cups available in the market.
Stainless Steel Sippy Cups
Pros: Stainless steel is healthiest material for a sippy cup.

Pura Stainless Bottle With Silicone Nipple & Sleeve 5Oz
Go New Mommy’s Choice
In my opinion, Pura Stainless Bottle with Silicone Nipple & Sleeve is the winner of the best sippy cup. It is made of stainless steel and silicone, it is 100% plastic free. The size of the cup is 5 oz and it is a perfect size for a baby to hold. Also, you can keep the nipple and spout from 5 oz bottle and use them with 9 oz bottle later. With a 9 oz bottle, you can simply swap a straw with a spout, a nipple or a lid, they all fit to the cup.
Pura Stainless Bottle is made from a food grade stainless steel, medical grade silicone components and no plastic parts. Their infant size cup (9 oz) is too big for an infant who is starting training drinking from a cup so this 5 oz bottle will be a good training cup. The cup comes with a nipple, therefore, you should purchase the spout separately to make this as a training cup. They sell a straw component separately as well. However, straw is not for this 5 oz bottle but their 9 oz cup. This cup is recommended to use with cold beverages only, not hot ones.
Pros: The cup is made of food grad stainless steel and medical grade silicone components with no plastic parts.
Cons: This cup comes with a bottle nipple so a spout needs to be purchased separately to use it as a sippy cup. Pura sells a straw part separately but it won’t fit this 5 oz cup. It only fits their 9 oz cup if you want to use it as a straw cup. If your baby is a little older, you can just purchase the 9 oz straw cup.
Plastic Sippy Cups
Plastic sippy cups are very widely used. They are often BPA free and light for a baby to hold.
Pros: Plastic cups are light, have cheaper prices and more choices in style.

Sippy Cups With a Straw
Many parents skip a sippy cup with a spout and start with a straw cup. A spout cup may be easier for a baby to suck the liquid out but the baby has to learn to tilt the head to drink out of the cup. For a straw cup, the baby doesn’t have to tilt the head but she has to learn to use the straw. The straw part is little hard to clean but you can purchase the cleaning brush for the straw separately.
