This sounds exhausting, especially for your wife. **Needing to be held to sleep is common at this age, and it doesn’t mean you’ve caused a problem.** Sleep rhythms are still developing around three months. You can start gentle crib practice now; formal sleep training, including timed crying methods, generally waits until at least four months and a discussion with your pediatrician.

Here’s a manageable approach:

- **Start with one nap a day.** Choose a time when he’s fed, comfortable and getting sleepy. Use a short, repeatable routine, such as a diaper change, dim lights and a lullaby.
- **Help him settle, then try the crib.** At this age, it’s reasonable to rock or feed him to sleep before transferring him. Falling asleep independently can develop gradually.
- **If he wakes, soothe him responsively.** Try a quiet voice and gentle touch. If he becomes upset, pick him up, calm him and try again when you both feel ready. Keep attempts manageable.
- **Share the settling work.** You can take over holding and crib attempts after feeds so your wife gets a dependable break. A trusted relative can help too.

**The immediate safety priority is a separate sleep space beside your bed.** For every nap and nighttime sleep, place him on his back in a crib or bassinet with a firm, flat mattress and fitted sheet; keep pillows, blankets and toys out. Share your room for at least the first six months. Bed-sharing raises the risk of suffocation and sleep-related death, particularly under four months. Avoid falling asleep while holding him, especially on a sofa or armchair.

Bring this up with his pediatrician, especially if lying down seems painful, feeding is difficult or weight gain is poor. For now, aim for small opportunities to sleep in the crib and regular breaks for both parents. He may still need considerable help settling and feeding overnight.
