Hi, My DS is 5 1/2 month old. He's started not going down to sleep until about 9pm, even though he's exhausted. I have to feed him and feed him, then he just sleeps on me. I've tried formula, which he gulped down, has a few breastfeeds and still does the same! I thought I'd try PUPD, but he's still screaming after nearly an hour. I've even tied putting him back on the breast because I thought he must be starving, but he just seems to want to drop off on the breast. He wakes up as soon as he's put down. My first son was a terrible sleeper for almost 2 years and it nearly caused me to have a nervous breakdown. We almost didn't have another one because of it, which is why I am trying to nip this in the bud. Now we're here again! I don't know whether to persevere with sitting with him while he screams or to give in.
