It is bad if you accidentally put an extra scoop of formula in the bottle although if it's done just one time it won't harm the baby.
If you accidentally put an extra scoop of formula in the bottle it could result in possible digestive issues, constipation and even dehydration.
Although if it just happened one time and you feed your baby the formula with the extra scoop of formula it won't hurt the baby but doing so a lot could lead to issues.
I've accidentally added an extra scoop of formula to my baby's bottle and he was just fine and it has happened a few other times when I was tired but in other cases I added the correct amount.
But if done too much it could result in dehydration as over concentrated formula can result in water being drawn out of the baby's tissue and lead to dehydration.
To prepare formula for night feed make the formula as you normally would in the bottles and then shake the bottle to mix the formula and place the cap on the bottles and store the bottles of formula in the refrigerator or in a mini fridge in the room where the baby is.
If making the formula fresh you should ensure the water is boiled and cooled down to a lukewarm temperature before mixing the formula.
For prepared bottles of formula they should be stored in the back of the refrigerator, where it's coldest and below 40 F.
Formula made and stored in the refrigerator can last 24 hours although it's best to use it within 2 hours of preparation and 1 hour from the start of feeding the formula.
You can pre make bottles for night feed and keep the bottles in a mini fridge or your normal fridge.
Formula when made with cooled and boiled water and kept refrigerated can be safely kept for 24 hours.
I always kept a mini fridge in my room with the baby as well and would keep their formula pre made in the bottles for night feedings which made it quicker to feed them and get them back to sleep.
After feeding your baby you should sit your baby up for 15 to 20 minutes long to help prevent gas and spitting up.
After you feed your baby they should sit up for 15 to 20 minutes and should also be burped to get rid of some of the air and also burp your baby frequently during feeding and after feeding.
Hold your baby upright and lean them slightly forward and if your baby has reflux you may need to sit them upright for a bit longer.
If yoru baby seems content and has not spit up, you might gradually reduce the upright time.
The age that reflux peaks in babies in between the ages of 4 months to 6 months of age.
Reflux and spitting up is common in babies and a normal thing as the muscle that prevents the stomach contents from flowing back up into the esophagus also known as the lower esophageal sphincter or LES is not yet fully developed in young babies.
As the baby grows and their lower esophageal sphincter strengthens, the reflux usually gets better and often resolves by the time the baby is 12 months to 18 months old.
A happy spitter is a baby that spits up frequently but is otherwise healthy and also content.
Happy spitter babies often gain weight very well and are not bothered by the spitting and they don't show any signs of discomfort or pain.
Spitting up is a normal part of the infants development and is also often called GER or physiologic gastroesophageal reflex.
A baby spitting up is very normal and does not mean anything is wrong with your baby unless they cannot keep any formula down at all.
Most babies will naturally spit up in the first few months of their life.
And the spit up is often a result of the muscle that is at the top of the baby's stomach also known as the lower esophageal sphincter not being mature fully and closing tightly, which allows for the stomach contents to come back up.
The signs that your baby is a happy spitter are the baby is eating well and gaining the appropriate weight and they are thriving even though they are spitting up.
Babies that are also happy spitters are not bothered by the spitting and don't seem distressed or don't seem to be in pain during or after the spitting up.
And some babies that are happy spitters are also happier and feel better after spitting up.
Happy spitters also tend to spit up frequently even with every feeding.
Spitting up can be a concern if the baby is frequently vomiting which is projectile vomiting or forceful vomiting or they are not gaining weight, can't keep any formula down or are showing signs of pain.
It could in those cases be a sign of GERD or another issue and if so you should see the baby's pediatrician to be safe.
