Oh no! Nicholas is almost 4 months now and has just started the same thing. He is waking every half our or so from about 1am onwards. I thought it was because he has had a cold, but it is still going on! Tonight, I have put a heater in his room to see if that helps. I am pretty strict with the bed time routine, same time every night, bath/shower - bottle - story - cuddle and into bed, and I can't thinkof anything else that may have changed for him, but just when you get used to them doing something, they change it!

Good luck and hugs to you :hugs:, I hope things get better for you soon and you get some sleep
