My son grew out of his next to me weeks ago, we ordered a big cot from argos that was meant to be delivered the next day. The mattress came but the cot never did. Turns out it was lost in transit and it took 4 weeks to come. This meant we had to cosleep for 4 weeks, now the cot has come the past week has been awful! He will go to sleep in it but is then awake every hour slamming his legs down. As soon as you pick him up and bring him over to our bed he’s straight asleep. Is there any tips to get him to stay in there?
