Hi all, I'd appreciate any advice. My 7 month old used to sleep through 9 or 10 hours a night, waking maybe once for a feed. The last week or so he has woken multiple times per night crying, refuses milk, and struggles to settle even when held/rocked etc. Have tried co-sleeping but this doesn't work either so he just cries in our arms until he is hungry enough for milk at which point we feed to sleep and can then put him back in his crib. He does this every 3 hours. He doesn't nap for very long during the day (3 x 20-30 min naps even if rocked he doesn't seem to be able to connect sleep cycles for naps) so maybe it's over tiredness contributing. Any advice appreciated.
