The usual advice is...
Watch for signs of tiredness - apart from the eye rubbing when my baby is really overtired, it looks the same as crying for anyone her reason,
Put the baby down drowsy but awake - not sure what this even looks like. The only time my baby is drowsy is after a feed, but...
Don't feed them to sleep - My baby is half asleep through pretty much every feed, despite very attempt to wake her throughout. It's so much easier to feed to sleep (plus Inget sleepy too so am not with it enough to do anything about it!)
Sleep in the same room but on a separate surface - So baby is too big for a Moses basket and never did sleep long in one anyway. Could buy a side sleeper cot but it's now a lot of expense for only a couple of months' use. Tried the travel cot, won't settle. So sharing a bed is risky and so is putting them in a separate room before 6 months old. Running out of options!
