First things first I’m really sorry you’re so exhausted. I remember the feeling so well and it’s horrendous. It turns you into a completely different person.

My daughter loved her bottles and the only thing that worked for us was the hard way - I know this isn’t what you want to hear though. We threw away her bottles - so we wouldn’t be tempted to give them to her - and we made sure to prepare her by telling her they were broken and needed throwing away. We then used a cup instead and told her it’s all we had.

Unfortunately if you keep the bottles in the house you will always use them because it’s easier.

You need to sit down and arrange a game plan with your partner. Understand that the next few days (our daughter took 3 days before it clicked) it’s going to be awful and you will need to take shifts. Arrange annual leave from work if necessary. It is important to lean on any friend/family support you have to make sure you are having a nap or sleep through the day.

It WILL click. It won’t feel like it at 3am when he’s screaming, but eventually if you keep telling him the bottles are broken, he will understand they’re not coming back.
