not sleeping!

Jessica

my 3 month old is having a hard time falling asleep and staying asleep! I'm not sure if it's sleep regression or if he is teething. It's early for both of those according to everything I have read but I'm not sure what else it is. not knowing is making it a nightmare for me to help him! He will only nap for about 40 min or so during the day and only for 3 hours at night. Has anyone else gone through this? Any advice?
