I have identical girls (7.5 months) and one is an amazing sleeper, the other, not so much! DT1 settles well, has 12 hrs at night and about 3hrs of sleep in the day. DT2 wakes at 5:30am & probably has 2x 45 mins in the day. She knows how to self settle, and for months I've been stressing about her routine, trying to tweak things & get it 'right' in order for her to sleep more.
But her sleep hasn't changed & now I'm just thinking that maybe she doesn't need much sleep? However I don't get why her sister needs so much more sleep? I would have thought they'd have a similar biological need for their amount of sleep?!
Anyone else with Id twins that are very different in their sleep habits?
