My son never sleeps on his own. He's 5 months old and likes me to do the "hele" always. But he's getting bigger and heavier. How can I make him fall asleep without it? (We don't use bottles and sometimes, direct latch doesnt make him fall asleep)

Look for other ways to soothe your baby without you exerting so much effort. It's also important to find a new soothing routine that you know you can sustain. Kasi if develops as a habit, mahihirapan ka ulit and then you'll find another way again. Try tapping. Some babies like it harder while some like it softer. Some babies love taps in sync with the beat of the heart. My sister discovered it effective for my baby when he was only a newborn, and she said maybe it's because he's used to hearing my heartbeat and it makes him calm.
