My baby sucks their thumb to fall asleep. Should I allow this, or will it be hard to break the habit later?

Thumb sucking is a natural and powerful self-soothing method for babies. Most discover it in the womb and continue using it after birth, especially at sleep onset to help them relax.
Short term: It's fine to allow this. It can actually help your baby develop their own ability to self-soothe and fall asleep independently — and unlike a pacifier, it won't fall out of the crib.
Long term: Thumb sucking usually becomes a real concern once permanent teeth start coming in (around age 4–5), especially if it continues past age 5–6. Until then, it's generally considered harmless.
Practical tip: You can relax for now. As your baby grows (around age 2), thumb sucking usually decreases on its own. When that time comes, you can gently guide them toward stopping by offering distractions and encouragement without pressure. Trying to force them to stop now creates an unnecessary power struggle and is often unnecessary.
