I'm really quite concerned about this... DP woke up this morning at 3:30am to find DS (2yrs 5mth) in bathroom... he'd obviously been downstairs too as the laptop had moved... I didn't hear anything and DP only thought he'd heard something... I'm really worried as to what he could be getting up to, such as playing with things he shouldn't or falling and hurting himself. Is he too old to be "forcefully" (ie. babygate) kept in his room? He doesn't come into our room when he wanders (it's happened before), just goes to bathroom or downstairs. Any other mumsnetters had this problem and solved it?! Thank you wise ones!
