YUP!!! and it did'nt take long for him to start giving excuses either (was'nt tired, needed a drink, heard a noise, wondered why we were't in bed, needed the toilet, even though he was still in a nappy???)safety gate helped..until he realised he could push it down..so then it got screwed in!!! which resulted in him yelling and screaming at it for hours very distressing,in the end we bought a torch, gave him some special toys and books that were only for his room at bedtime and he just seemed to grow out of it..
Oldest DD no problems, next DD no prob, but I reckon with little DD 18 months old we may have a similar issue, she currenlty is in a cot/co sleeps and wakes up a lot during the night, so i can see when she gets into a bed she will just hop up when ever, not bad if you are in bed but a real hassle, if it still early!!!!
Goodluck they do grow out of it eventually...??????????????????????
