I have tried the swing but not a bouncer? Do you think that would make a difference?
I think a swing holds a baby in a different position (more upright and sometimes hunched - like a csrseat) to a bouncer (which is more reclined).
Also you get no control over the movement of a swing. By foot bouncing a bouncy chair, you are entirely in control to respond to tiny changes in behaviour by increasing/decreasing tempo, verocity or speed of the bouncing. Then to gradually reduce it over time.
In short, I would definitely recommend a manually controlled bouncer that you can bounce with your foot.
I also think that DD has a hard time letting go when it's daylight so should I put her in a dark room for her naps initially?
If you want. I think you get better long term sleep habits if baby learns to be able to go to sleep with some background noise and light. Especially useful if you expect your child to have a sibling in the near future.
Baby does need to sleep in the same room you are for daytime naps until 6 months. For this reason they are usually done downstairs. If you wish to spend your baby's naptime ditying in a dark room yourself, that's fine. I can't see any huge benefit in doing it at this age though, but also no harm.
If you are planning on doing naps downstairs in the daytime, then by all means draw the curtains and switch down the TV if ypu wish. Again, this doesn't actually make much positive difference to long term slerp habits, but its fine if ypu prefer.
(When I had DC2, so determined was I that he wouldn't be the light sleeper DC3 would be that I deliberately positioned his sleep posotion by the bright window, lights on in addition, telly, unabated toddler noise. All so he learnt from early on to sleep through everything)
And should I just put her in the bouncer and then see if she will fall to sleep just like that?
She's unlikely to go to sleep "just like that". It requires some work to get baby sleeping independantly. Dummy reinserts, lots of consistant, rhythmic bouncing relentlessly and often.
It takes some (often a lot) of effort to get baby to sleep. Just putting baby in bouncer and waiting is very, very, very unlikely to have baby happy or sleeping.
And what would you consider a good length nap? Is approx. 40min ok?
At 10 weeks 30-60 minute naps would be normal. This may well reduce over the coming month whereby 30-45 minute naps are the norm. Awake time of around an hour between naps.
Do you think I should initially make sure she has her naps at the same time every day?
Having a consistant (7 days a week, 365 days a year) wake up time in the morning is useful. Aside from that, be baby led according to nap length by limiting awake time.
I wouldn't want more than 1h awake at this stage, with varying awake times depending on the length of the previous nap. I had 45m awake time as my average at 3-4 months old. If nap was shorter than normal, shorten awake time to maybe 30m. If it was a longer than normal nap, extend awake time to maybe 60m.
Be baby led in setting awake times, all babies are different. Mine are just examples becsuse of you are a FTM you may have no idea what the norms are. Awake times extend with age, development and as naps extend - so it is a state that is constantly changing as your baby grows.
And at what point will she be able to stay awake for longer?
Depends on the child. Sleep changes quite significantly around 3-4 months old and after this point naps of 1 sleep cycle are normal. But baby can learn to link sleep cycles. Good sleep habits and established methods to resettle baby back to sleep make extending naps easier.
Some babies have habits in place to link sleep cycles in place ready for when the regression happens at 4 months and such children go straight to long naps without any trouble. Other babies struggle to learn to link sleep cycles and as such short nsos can remain for many, many months.
Generally speaking longer naps of the passive newborn sleep last until 2-3 months. Shorter naps develop from 3-4 months and then baby learns to link sleep cycles, so naps extend again at some point between 3-13 months. Huge variety at this point comes from the fact that there is a huge variety on the sleep habits of babies at this point and some are less consistant with helping naps extend compared to offer habits. My children were around 5 months old when naps extended.
I have read somewhere the windows is 1-2 hrs so I have been trying so stick to that pending her mood.
I'm not sure what window you mean? Awake time window does not want to be as long as 2h unless you are getting naps of 90 minutes plus. Even then I'd only go to 90 minutes awake time at this age, even with long 90m+ naps.
