My DS will be 5months next week and for the last 12 nights he has been waking between 5-10 times and crying/screaming instantly. Before this he slept so well, only waking once a night since 5 weeks for a feed between 6:30-6:30 and he wouldn't cry, just open his eyes and babble. He has a dummy and it instantly settles him but this could last 5 minutes or a few hours, we just don't know. With out DD we got rid of her dummy at 5.5months as we had to keep giving it to her, but then she still wasn't a great sleeper after and we would end up being in with her to settle her for hours sometimes. Should we get rid of DS dummy to help with settling himself or would it be better to just let him keep it and instantly settle him using that? I just hope this sleep regression doesn't last for months!!!
