DD2 is being a bloody demon at bedtime at the moment. She's 3 in November and we took the sides of her cotbed a couple of months ago. Since then she's been getting up relentlessly after we put her to bed, sometimes for 2-3 hours. We've tried telling her off, removing her toys, ignoring her etc but her behaviour keeps getting worse. She now keeps also deliberately waking DD1 up who is in the room next to hers by going into her room and jumping on her when she's asleep. Ironically she's clearly exhausted and eye rubbing and whingy and clearly needs to go to sleep, but just won't give in. We're literally getting up to her every couple of minutes to her in the evening and it's meaning me and DH aren't getting any time together of an evening, and it's really getting us down. This evening I finally cracked and jammed the lock on her bedroom door so she couldn't open her bedroom door or leave her room. She screamed and tantrumed for a bit, but then gave that up after 10 mins and 5 mins later was asleep in her bed. Now she's asleep I'll unjam her door so she can get out if needed in the night / morning. I know it's not great parenting, but I'm at my wits end. I'm hoping after a few days of not being to get out of her room she'll just give up on trying the door and stay in bed. Please tell me I'm not the only one who has ever resorted to this?
