2year old getting up during night

[Samcookie]

Hi all

Need some advice regarding my 2year old Boy.
We’ve had him in a good routine since being out of lockdown as our routine was all over the place during lockdown. He’s been going down around 7:30/8pm depending on the day as he goes to nursery 3 days a week. He spent a week in Scotland about 5weeks ago now visiting family and had to sleep in the bed with my partner. Since coming back he wakes 3/4 times a night trying to get into our bed. I 90% of the time take him back to bed but I’m getting exhausted now. We also have a 8month old boy And he sleeps great only wakes once a night for a bottle.
I need ideas on how to make him want to stay in his bed!?
