I had a very good experience with the sleep wave method at 5 months - suggest you look it up. It took three nights of not much crying before he was sleeping through with two brief breastfeeds over night.
the key before applying any sleep training method is to ensure that your baby is not having too much day sleep and has an adequate amount of time awake between the last nap of the day and bedtime. At 7 months for most babies I’d say 3.5-4 hours. If you track sleep you can get an idea of how much they need per 24h, then allow 10-11h for nighttime and the rest for naps.
It’s not true that babies can’t self soothe, they can. My son went to sleep in half the time once he was in a good routine and I gave him some space to work it out. He plays with his sleep sack for a minute or two and goes to sleep. He absolutely resists sleep if you try to rock him to sleep, he needs space.
its also not true that babies “give up” once sleep trained. They dont, they just stop calling for you to connect their sleep cycles for them because they’ve learnt to do it themselves. My son still calls if he’s in pain, or unwell. When he’s ill I sleep on a foldy bed in his room with him so I can be there if he needs me.
theres lots of noise out there at the moment that is anti-sleep training, and its all completely dismissive to the point of callousness about maternal mental health and wellbeing. It’s totally unnuanced and not evidence based, and makes gross generalisations about parents who do it. I adore my son; I am a responsive, caring parent, who has sleep trained.
All sleep training is is teaching your child to go to sleep without assistance. Sleep training has not been found to cause harm when applied at an appropriate age and in a developmentally appropriate way.
you deserve rest OP, so you can be the parent you want to be during the day.
