Hi all, looking for some help. We’ve been sleep training our daughter and it was all going well for a few weeks until Wednesday. She’s now refusing to sleep in the cot, there is hysterical crying which sounds more guttural than normal crying. Bedtime has been one night in our bed and two nights starting in her bed for four five hours and then crying and coming into our bed. Prior to this we had no crying at bedtime, had stopped feeding to sleep and at least once nap a day in the cot. Any advice welcome as we are not sure what to do or try. She’s just under five months and breastfed! Feeding has increased so not sure if it’s growth spurt or teeth but we’re at our wits end as she seems outwardly fine!
