Baby sleeping

Meryem

My lo is 6 1/5 months he has never been a great sleeper but this week it has been a joke he will not sleep he keeps waking up every 15 minutes crying. I’ll settle him and by 15 minutes he will start again I’m exhausted and don’t know if it’s normal for them at the moment , am I alone or is anyone else’s lo the same at the moment ?
