Thank you so much for your replies! Based on 12 sets of answers, this is what I can work out:
Child's first name: this is just so I know who I've recorded!
Boy or girl?: 58.3% are boys, 41.6% are girls
Age when started to sleep through: 66.6% slept thru by 6 weeks of age, 25 % slept thru by 8 weeks of age, 8.3% slept through by 10 weeks of age
Was this child your first child?: 83.3% were the first child, 16.6% were not the first child (though many second time parents might not be using this website)
At the time of starting to sleep through:
Was your child breastfed or bottle fed? 33.3% were breastfed, 66.6% were bottle fed
Number of feeds per day? 25% had 5 feeds per day, 66.6% had 6 feeds per day, 8.3% had 7 feeds per day
Was your child sleeping in your bed, a cradle, a bassinette or a cot? 0% slept in their parents' bed, 8.3% slept in a cradle, 41.6% slept in a bassinette (but many went to cots soon after), 50% slept in a cot
Was your child sleeping in your room, a room with another sibling or in their own room? 50% slept in their parents' room (but many went to their own rooms soon after), 0% slept in their sibling's room (but 83.3% didn't have siblings anyway), 50% slept in their own room
Was your child being wrapped for sleep? 58.3% were wrapped, 41.6% were not wrapped
Was your child of above average weight, average weight or below average weight? 41.6% were of above average weight, 58.3% were of average weight, 0% were of below average weight
Was your child being put to sleep in your arms, put to sleep by you in their bed or self settling in their bed? 0% were put to sleep in the parent's arms, 0% were put to sleep in their bed by the parent, 100% were self settling
Was the weather hot, cold or average? 16.6% slept thru during hot weather, 75% slept thru during cold weather, 8.3% slept thru during average weather
Did you have a regular bedtime routine and what was it? 75% had a regular bedtime routine (all routines were bath, milk, then bed, bedtimes ranged from 6:30 to 7:30pm), 25% didn't have a regular bedtime routine
What sort of sleeper was your child during the day? 75% were excellent day sleepers, 25% were average day sleepers, 0% were poor day sleepers
Anything else that may have contributed to your child sleeping through? a lot of the answers were very similar, especially giving a 10pm or 10:30pm roll over feed (either woken or dreamfed), then given water when they woke after that or resettled in the cot without picking them up, getting into a routine from an early age, and feeding often on a schedule rather than demand feeding. Other answers included the parents being relaxed, the baby being contented, a musical mobile, moving the baby to their own room and switching to formula.
In my opinion, the factors that seem to be showing a strong similarity are:
* sleeping in a bassinette or cot (91.6% combined)
* being of above average or average weight (100% combined)
* baby self settling (100%)
* cool weather (75%)
* having a regular bedtime routine (75%)
* giving a roll over feed
These babies also seemed to be excellent or average day sleepers (100% combined).
KirstieGai, was Madison 8 months or 8 weeks old when she started sleeping through the night on a regular basis? I haven't included Madison's results yet.
The results are really interesting, especially the fact that all the babies were self settling. We need to remember though that these results are only based on 12 babies so far and that some results may be coincidental.
Keep the replies coming!!! Thanks!!!
