My DS has recently started to wake up every night, either waking up shouting and babbling around 2-3am or waking up for the day around 5am. He always had the occasional night waking due to teething, random grumpiness etc but now it is every. single. night. It is driving me insane. My DH works long hours in a stressful job and it's affecting his work at this stage because even though I get up to settle DS he still hears him as he is very loud. He's tired every day and it's causing tension between us.
I've tried putting DS to bed later but that doesn't work. He goes to bed at 7pm already so I can't put him to bed much earlier than that. He naps once a day for about 1.5 - 2.5 hours, depending.
The worst of it is that he is dog-tired every morning now and a complete nightmare with his behaviour as a result. Once he has his nap his mood improves a lot so it's obviously tiredness. Up until this waking started he slept through until 6:30 / 7 most nights. I thought it was just a phase he was going through to do with language learning as he babbles so much when he wakes up but it's showing no sign of ending... it's not teething anymore either because he has 16 teeth now.
His sleep now is worse than it was 9 months ago! Any advice / experience?
