What recovery actually looks like
Your baby has been sleeping for a fortnight and you feel no better, which is frightening in a specific way. The lag between their sleep improving and yours is real, it is well documented, and it is not a sign that something else is wrong.

Sleep debt accumulated over months does not clear in a week. The body recovers in stages, and the stages have an order - some functions return quickly, others take considerably longer, and the ones you most want back tend to be at the slower end.
Meanwhile, several months of hypervigilance does not switch off because the noise stopped. Many parents keep waking at the times their baby used to wake, for weeks after the baby has stopped.
The order things come back
Physical tiredness, within a week or so. The heavy, aching exhaustion is the first to lift.
Emotional regulation, two to three weeks. Fewer tears over nothing, a longer fuse. Often the first change other people notice.
Concentration and memory, three to six weeks. Reading a page and retaining it. Finishing a thought. This is the slow one.
Interest in things, last. Wanting to see people, wanting to do something in the evening. Six weeks or more, and after a long debt it can be several months.
What not to expect
Do not expect to feel like you did before. Some of what changed is not sleep debt - it is a different life with different demands, and a baby who still needs you all day. Comparing yourself to your pre-baby energy sets a target that sleep alone will not reach.
And do not expect the improvement to hold uninterrupted. Teeth, illness, leaps and holidays will take nights back. That is not a relapse of the whole thing.
The nights improve and you do not, for a few weeks. That gap is normal and it closes.
Helping it along
A consistent wake-up time for yourself, daylight in the morning, a caffeine cut-off in the early afternoon, and going to bed earlier rather than reclaiming the evening every night. Slightly earlier bedtimes across a week recover more than one long weekend lie-in.
If you are still waking at 3am out of habit after several weeks, that usually fades on its own. If it does not, or if you cannot get back to sleep when you do wake, that is worth mentioning to your GP.
Waking out of habit
Many parents keep waking at the old times for weeks after the baby has stopped. It is hypervigilance rather than insomnia - months of listening for a specific sound do not switch off because the sound stopped - and it usually fades on its own within a few weeks.
What helps in the meantime is not checking the monitor when you wake, keeping your own wake-up time consistent, and getting daylight in the morning. If you are still waking at three after a couple of months, or waking and unable to get back to sleep, that is worth mentioning to your GP rather than waiting out.
Why it lags
Sleep debt built over months clears in stages rather than all at once, and the brain prioritises: deep sleep recovers first, then the stages associated with mood and memory. That is why physical tiredness lifts within a week or so and concentration takes a month or more.
On top of that, several months of listening for a specific sound does not switch off because the sound stopped. Many parents keep waking at the old times for weeks. Both of those resolve - but knowing they exist prevents the particular fear that arrives when the nights are finally fine and you still feel terrible.
When to stop troubleshooting
If you feel no better after two months of decent sleep, or if low mood, anxiety or an inability to enjoy things has persisted for more than a fortnight, see your GP. Exhaustion that does not lift when you rest is one of the clearest signs that something other than sleep debt is going on, and it is treatable.
