Pregnancy insomnia

Im 32 weeks pregnant and I have hit my insomnia stage 🤦‍♀️ my first pregnancy all I did was sleep this time I swear everything is complete opposite but I can only sleep maybe 3 hrs a night and I have a 5 year old to keep up with so I can’t just nap during the day whenever I want is there anything i can take that actually helps? I’ve always had sleeping issues but so far up until now was great no matter what I just can’t stay asleep or fall asleep 😩
