Co sleeping

My 3yo started cosleeping again when my baby turned 9mths. I think he felt left out because baby was in my room and we had just been on holiday visiting family where we all coslept together and he has asked to sleep in my bed ever since.

In his room he had been waking up every time bub woke. But in my bed he sleeps through most nights so I am taking that as a win.

When he originally moved to his own room the only thing that worked was consistency. Every time he appeared at my door I got up and said “ok let’s go back to bed” and walked him to his bed, cuddled until asleep and repeat and repeat. Slowly he woke less. If daylight started peaking through the curtains then he was allowed to climb into my bed for snuggles.
