I have 2 DC 5 and 2. Eldest was a bad sleeper but has slept consistently from 18m, very cautious and generally a very easy child, has never had a tantrum and spoke early.
DS2 has been sent to test me, worlds easiest baby slept through from 6 weeks old, self settled just an absolute dream. His speech is slow, he can say a few words and will repeat some more but is incredibly expressive and non verbally communicative. He is generally very quiet like my DH, but loves socialising. At about 22 months he learned how to come out of his cot and since then nights have been hell. We have tried to switch to a bed a few times but that was even worse. He settles in his cot after a few returns just before 7. Then he is up at maybe 2, 4 and up for the day at 6. But the problem is that he doesn't let me know he's awake, he never cries for us. He just gets up to mischief. He is really well coordinated and will climb to high shelves to get what he wants using chairs as necessary. We have a turn lock on the door plus a chain plus we now have a chime alarm set as he has managed to get it open once. We took him in with us for a couple of months but we were all waking each other up and it didn't make any difference and he would just silently leave the room then do the same stuff. I've had to remove the light bulb from his brothers room because he kept going in and banging the light on to wake him up. I've taken to strapping him in the pram when he wakes about 4 just so he can't get up to mischief and we can actually get some sleep. I take him to the park most days or soft play to get the urge to climb and explore independently out.
Has anyone had a wild child at night???
