Help with sleep for Toddler who just lost his Mother

Hi there,I'm (34M) looking for some assistance on my toddler (3M) and challenges with sleep since his mother (34F) suddenly passed away less than 2 weeks ago due to complications from Cancer.We have been pretty open with him from the beginning about what was going on, and that his mom had cancer and was getting medicine to fix it. When she passed, we brought him to the hospital and explained what had happened and how she died and her body doesn't work anymore (stuff they tend to help toddlers understand the totality of death). Overall, he seems to grasp the concept of death and that mom isn't here anymore and will never be here as best as a toddler might understand (...i honestly don't understand how this happened as an adult so I can imagine it's even tougher for a toddler).The main challenge that i'm having is around sleeping. I always did bedtime, and over the past several months I have been the primary caregiver to him so nothing is new in that department. He usually has dinner, plays, bath, stories and in bed by 8-830pm and sleeps 12 hours through the night every single night. However after the death, he refuses to go to sleep and seems to have so much energy. He did make a comment he was scared, but that might have been me leading him into saying that. he also has some separation anxiety (which i imagine is perfectly normal after a loss) and needs me to lay with him to fall asleep which he never needed to do before. Sometimes it's around 1130pm-1200am before he finally falls asleep which is way past his normal bedtime. This isn't the worst, however it's causing issues for me as I can't get any alone time to even begin to process or figure out my next steps. I don't want to, but have had to give him gravol a few times at night just to get him to fall asleep. I don't want to get into the habit of that, so i'm looking for other suggestions on things I can maybe give him to help sleep, or at least try and relax him. Someone suggested gummy melatonin, however haven't read up on that much yet. I know this is temporary, and it'll take some time before it gets back to normal, but just looking for assistance.Also, is it okay for a 3 year old to get approx. 10 hours a sleep a day? He tends to nap at preschool for 1 hour a day still at least, so just want to make sure he's getting enough sleep.Thanks, any help would be greatly appreciated. I'm just kind of at a loss right now and looking for any help I can get. via /r/Parenting https://ift.tt/2qEIeJT
