Hey all, I'm new to this forum. I have a 5-month old son who's been really, really hard to put down to sleep the last few days. I feel like his wake times are longer now because he protests when I put him down and then plays in the cot for 20 minutes until he cracks it and then proceeds to scream and cry for another 20 minutes. But I'm seeing all the tired signs, yet he's not tired. Are their sleep patterns meant to change around this age? Do I keep him up for longer or still try to settle him even though it's taking an hour?
