10month old not sleeping at night

Hi there , so my baby was a good sleeper and i had no problem but out off the blue he doesn’t want to sleep the whole night i give him capol and bongela for his theeth but i dont think thats the problem. He dose cry from pain he crys for me to take him out and play with him i am exhausted i have a 2 year old daughter with autism so by the time we done with the day im so tired i just want to sleep . I normally put him

To bed at 8:30 but iv changed it to 9 or 9:30 as I thought if i let him stay up a bit longer he be more tired and sleep through the night errrr WORNG ! He still wakes up and refuses to go back to sleep he will cry and scream! Untill i take him out i cant let him cry it out because i dont want him to wake up my daughter. Anyone has any ideas off why is he doing this to me 🙄🤨

Heh

Any idea of what i can try and do to keep him asleep will be appreciated 😘
