3 year old sleep regression ?!

Kaitlynn

Is 3 year old sleep regression a thing? My son has always slept in his bed since he's been born and also a great sleeper usually will go down at 8 and sleep through the night till 6:30-7 in the morning but here lately bed time has been a complete nightmare! He wants in bed with me and his dad every single night and will throw a full on tantrum untill hes with us. I know hes tired because he will literally fall asleep as soon as hes next to us and sleep all night. I dont want to start the habit of him being in our bed every night we have a baby coming in march and between him kicking me all night long and a new born i will never get sleep. We have got him on a strick bed time routine so every night its dinner bath books and then bed but the last week its been a complete meltdown. What can i do to fix this and help him ?!?!?! I feel horrible!
