Sleep Regression and Milestones: Is There a Link for Your 3-Month-Old?

Not medical advice. For emergencies, call your local emergency number.

The transition to 3 months can be a tricky one for both parents and babies, especially when it comes to sleep. Many new parents notice a significant change in their baby’s sleep patterns around this age, often accompanied by new developmental milestones. One common observation is that babies who are learning new skills, like sucking on their hands, may start fighting sleep more than usual.

This phenomenon is often referred to as a ‘sleep regression.’ While it’s not a formal medical term, it describes a period where a baby who was previously sleeping well suddenly starts waking more frequently, having trouble falling asleep, or taking shorter naps. Several factors can contribute to this, including developmental leaps, increased awareness of their surroundings, and changes in their sleep cycles.

For a 3-month-old, learning to suck on their hands is a significant developmental milestone. This self-soothing skill can, paradoxically, disrupt sleep in the short term. Babies may wake themselves up when they realize they can suck on their hands, or they might become overstimulated by this new sensory input.

So, is there a real link? Yes, it’s very common for developmental milestones to coincide with temporary sleep disturbances. The key is to understand that this is usually a phase. By providing comfort, consistent routines, and a supportive sleep environment, parents can help their babies navigate these changes. If you’re experiencing this with your little one, remember that patience and consistent support are crucial. Snugs.ai can offer personalized tips and guidance to help you and your baby through this period.
