I've posted about this a few days ago in the Behviour thread but not sure if that was the right place so I'll try again here. Basically, DS was going through the night (approx 11h) really well - pretty much every night from being 10 weeks old. At 12 weeks he caught a cold and had his 12 week jabs and basically hasn't been the same since and is now waking in the night again for a feed or feeds. We also went on holiday for a week over Christmas and I think this may have disrupted him too.
I was wondering if he's been having a growth spurt but his stomach hasn't grown as fast as the rest of his body. I try to feed him 7oz every 3-4 hours through the day (ie. 5 feeds/day) but he rarely finishes them. He then has a full 7oz bottle through the night and sometimes wakes a second time for about 4oz. Could it be because his stomach's too full through the day to take any more so needs to wait until it's empty again (ie. at night) before he can take any more?
I'm feeling a bit frustrated with all this as I know that he can go through the night, as he showed a few weeks ago. Does anyone else have experience of this and will it sort itself out naturally? If not, is there a way of trying to ease him towards taking more through the day? Thanks
