Consult with Pediatrician physically for further evaluation and treatment

If your baby is only sleeping 10 hours in 24 hours, it’s slightly less than the typical range for their age, but some babies may naturally need less sleep. However, it’s important to ensure your baby is not overtired, as this can make it harder for them to sleep well. Look for signs like irritability, frequent crying, or difficulty settling to sleep. If your baby seems content, active, feeding well, and meeting developmental milestones, it may just be their individual sleep pattern. To encourage more sleep, try establishing a consistent sleep routine, ensuring the sleep environment is calm and dark, and offering naps or quiet time at regular intervals. Naps during feeding is common in some babies, as can be soothing and help them fall asleep. However, this pattern can sometimes lead to shorter, fragmented sleep and might also indicate that they’re not fully feeding during each session. To help, try encouraging more complete feeds by keeping your baby awake and engaged during feeding—this could include gently stroking their cheek or switching breasts to maintain interest.
