@Anna, thank you for writing to us. I am sorry your son has been teething, it can be such a challenge when that starts! Here is a link to an article we wrote about sleeping and teething: https://www.babysleepsite.com/sleep-training/teething-sleep/
Your son is still pretty young so you probably haven’t done any kind of formal sleep training just yet, and may not be on a set schedule, but here is a link to another article about 3 month old sleep: https://www.babysleepsite.com/schedules/3-month-old-baby-sleep-and-feeding-schedule/
At this age he is still going to be sleeping quite a bit, so no worries if he is napping a lot if he is still eating as much as he should. There are lots of developmental milestones that happens as well that could be contributing to his sleepiness. Once he hits around the 4-6 month marker, he will begin to develop the skills to put himself to sleep, but it is possible he will have a crutch to falling asleep while nursing. This is normal and does not mean you necessarily need to change anything now, but I did want to mention it so if it becomes a problem and something he needs in order to sleep for you to be aware he is old enough to teach to sleep on his own if you would like. Here is an article on that: https://www.babysleepsite.com/sleep-training/sleep-association/
Thank you for using the Baby Sleep Site as a resource for sleep! I hope he finds some relief soon!

@ lenka – what about Snoozeshade? Have you heard of these? They make portable black-out products – covers for strollers, car-seats, etc. That might be an option… You might also try and make sure, on days when he doesn’t nap well due to not being in a dark room, you offer early bedtime. I’d also suggest that you aim for about 4 “dark” naps a week – that still gives you flex time to go and run errands and have fun, but he probably does need the majority of his naps at home, in the dark.

Hope that helps, lenka – thanks for commenting!

Hope these resources help, ashlee!

@ Brenda — We have a post on just this topic, actually! You can check it out here: https://www.babysleepsite.com/baby-naps-2/why-baby-and-naps-different-than-night-sleep/ Also, bear in mind that it’s pretty unusual for a 3 month old baby to sleep 9-10 hours without a feeding. So if you find that she’s nursing a lot during the day, consider it normal; she needs to store up on food in order to sleep such a long stretch at night.

Finally, keep in mind that most babies don’t develop consistent napping schedules until they’re closer to 6 months old. So erratic napping at this age isn’t unusual.

If you want to work towards more predictable and consistent naps, you could check out our free napping guide, available here: https://www.babysleepsite.com/free-baby-nap-guide/

Hope this helps, Brenda! Thanks for commenting. 🙂
