advice from moms please

So my daughter who is 18months old has always slept in our room in her crib, I’m currently 6 months pregnant , and this last week she hasn’t been sleeping (due to her molers coming in) well my husband has been super grumpy because of her sleep regression which I don’t blame him because he is our main income , our daughter has a room , I’ve just always kept her in ours ( we have a lot of space ) but she does seem to get distracted at the tv etc. HOW do you find peace with moving your baby in their own room. I can’t imagine putting her in another room and not being able to check on her right away. I could invest in a baby monitor but I’m nervous to trust a device. Any advice ?
