DS sounds utterly shattered but I agree, shouting at a small child is not on. The sleep/nap diary sounds a good idea, as does a chat about how you are all feeling. You may be right and there may be another issue but equally working long hours and not sleeping is enough of an issue for anyone.
Regarding the sleep problems, I would consider the following:
- Is this a problem for the child? Many reported sleep issues are, apparently, only an issue for the parent and the child's behaviour may well be perfectly normal in another family. Who really has the problem? If it's not the child then the adult needs to find some coping strategies.
- What's bedtime like? If a daytime nap isn't affecting bedtime then the night waking is unlikely to be connected.
- What else is going on? New siblings, new nursery, moving etc etc can all unsettle a child and lead to night waking or wanting to sleep with a parent. This is fairly normal and relates to how secure the child feels.
- Is the napping a daily occurrence or only when he's ill? If it is sporadic and he's sleeping after 1pm then it may well cause problems because the child feels unsettled.
- What coping strategies could you use?
Bedsharing - There's a massive difference between electing to bedshare and not which can feel like an invasion. Bedsharing can help reassure unsettled children but equally an already unsettled child being rejected is not going to help. The two parents need to decide what is acceptable and how it will be managed. You may all decide on a period of bedsharing or not.
DW may decide to sleep elsewhere for a bit, either to facilitate bedsharing or just to be removed from what is a source of anxiety for her.
Introduce napping or quiet time at a specific time to give rest. Between 2-3years old most (but not all) children drop their nap. This does not always happen gradually and most children still need some rest time even if it's not sleeping. Watching a DVD or something on CBeebies or reading a book together can all be restful without sleeping.
Have a cut off, say 1pm after which time unless he is ill you will keep him awake until bedtime.
Avoid car journeys or buggy rides after the cut off because they will make children sleep.
Have an agreed plan for evenings when he has napped. If you know it will mean a late bedtime then plan for that.
Move bath time to the nap "danger time". It will help keep him awake but won't add extra work to your day.
Keep him on his feet if he looks tired and you don't want him to nap. Go out for a walk, a kick about or some other activity.
