Sleep help

Rebecca

My little boy has always held to sleep which always worked but when he was 11/12 months started needing to be held for longer and kept waking up more in the night so tried sleeping training using the cry it out/ controlled crying which he just cried until he was physically sick and so stopped as I didn’t want him making himself poorly. Ended having to put him in bed with me as that’s the only way we could both sleep but I’m wanting to get him back into his bed and self settling and was after some advice and tips on how to do so with as little distress as possible. He’s 15 months now and very attached to me as partner works away from home and with the pandemic and lockdown doesn’t really see anyone else so just me and him everyday x
