Babies do some truly weird things. One moment, they’re staring at a wall, the next, they’re smacking their lips or even laughing in their sleep. As a parent, it’s easy to wonder, Is this normal? The good news is that most of these quirks are completely harmless and just part of your baby’s development. Understanding these behaviours can help you relax and enjoy watching your little one grow.
Making Strange NoisesBabies are tiny noise machines. From grunting and squealing to gurgling and growling, they love testing their vocal cords. These sounds may seem odd, but they’re a normal part of development. Grunting often happens during digestion, and squealing is usually a sign of excitement. Unless these noises come with signs of distress, they are nothing to worry about.
Waking Up StartledHave you ever noticed your baby suddenly flail their arms and legs while sleeping? This is called the Moro reflex, a completely natural response that usually fades by 4–6 months. It might seem alarming, but it’s actually a sign that your baby’s nervous system is developing properly. Swaddling can help reduce these sudden movements and promote better sleep.

Babies often fixate on seemingly blank spaces like walls or ceilings. It might make you wonder if they’re seeing something you can’t! But don’t worry—babies are drawn to light, contrast, and movement. Their developing vision makes patterns fascinating, even if it looks like they’re staring into space.
Smacking Their Lips or Sucking on Their HandsMany babies smack their lips or suck on their hands, even if they’ve just eaten. This is usually a self-soothing behaviour or a way for them to explore their mouths. Sucking is a natural reflex that helps babies feel comforted and secure. It’s completely normal and not a sign that they’re still hungry.
Head Banging or RockingIt can be unsettling to see your baby bang their head against the crib or rock back and forth, but this behaviour is often a way of self-soothing. Many babies do this to help themselves fall asleep. It usually peaks around 18 months and disappears by age three. As long as they’re not hurting themselves, it’s nothing to worry about.
Difficulty FocusingNewborns sometimes cross their eyes or seem unable to focus. This happens because their eye muscles are still developing. By 3–4 months, most babies can track objects properly. If persistent eye-crossing continues beyond this, it may be worth mentioning to a doctor, but in most cases, it’s just a temporary phase.
Pooping in Weird ColoursBaby poop comes in all sorts of colours—mustard yellow, green, even black in the early days. This can seem alarming, but most colour variations are completely normal. Diet and digestion play a big role. Greenish poop often comes from iron-fortified formula, while yellow and seedy stools are common in breastfed babies. Unless you see blood, mucus, or signs of distress, there’s usually nothing to worry about.
Laughing or Crying in Their SleepBabies often giggle, whimper, or even cry while sleeping. This happens during REM sleep, which is when dreaming occurs. Since babies spend a large portion of their sleep in this stage, it’s completely normal. It doesn’t mean they’re in pain or having bad dreams.
Pulling at Their EarsEar pulling is something many babies do, and it can make parents nervous about ear infections. While ear infections can cause discomfort, most of the time, ear pulling is just a sign of teething or self-exploration. If there’s no fever or fussiness, it’s likely nothing serious.

Around 4–6 months, babies discover their feet—and once they do, they can’t get enough of them! They’ll grab, chew, and play with their tiny toes, which might seem odd but is actually a sign of good motor development. It helps improve hand-eye coordination and body awareness.
Fascination with Repetitive ActionsBabies love doing the same thing over and over—whether it’s dropping toys, banging objects together, or making repetitive noises. While it might seem monotonous, these activities are actually helping them learn about cause and effect. They are also great for improving motor skills and coordination.
Exploring Everything with Their MouthBabies put everything in their mouths—hands, toys, blankets, even their parents’ fingers! While this can seem unhygienic, it’s actually a natural way for them to explore the world. Mouthing objects helps with sensory development and provides relief during teething. Just make sure everything they chew on is clean and safe.
Final ThoughtsBabies do plenty of weird things, but most of them are just part of growing up. Understanding these little quirks can help you relax and enjoy every stage of your baby’s development. As long as there are no concerning signs like fever, excessive fussiness, or injury, these behaviours are perfectly normal. Parenthood is full of surprises, so embrace the weirdness and enjoy watching your baby grow!
