I need help

[CarlyRose80]

This is what my nights are like and they are becoming worse. I don't know what to do anymore and I'm exhausted. This is an 18 week old
Bed at 8 then woke at these times 10.30. 12.15. 1.15 fed. 1.35 back to bed. 3.30 4.50 5.45 and about to have a feed. I kept track of times as I woke up. It's ridiculous and I exhausted.
What can I do to encourage good sleep. He wakes for his dummy I'm assuming as he goes straight off.
I hope this is a phase and passes soon. We are away I'm holiday next week and I'm dreading it. :-((

Hi thanks. Yeah I've had white noise for him since he was quite small to help with day time naps. I've just started using it for night but still with no affect. Last was sleep at 9. Woke at 10. 11.30. 12.30. Offered food at 1/30 and took an ounce. Then slept for 2 hours till 3.30, then every hour till 5.30 then slept till 7 where we are now up. he had his bottle at 5.30 which was a 3oz!
I am still clueless. Done the swaddling thing and it just depends on his mood when he goes to bed as to if he will tolerate it but even when he is swaddled he still wakes the same.
