   A heavier plane has more momentum (when thrown at the same speed),  but it's also got more downward force acting on it. If it has the  same wing area, though, it has the same lift, so it drops more  quickly than a light plane (objects fall at the same speed only in  the absence of air resistance).
By 2 months, baby's bedtime should be between 6:00-8:00pm and should occur about 1 hour after the last nap ends. 3 months: babies this age should be on a solid 4 nap schedule with the last nap of the day ending by 5:00pm.
Share. My 1 year old has been on a bedtime routine for a couple of months now and at first seemed to solve her sleeping problems (Waking up several times a night).Still, my husband and I often hear her wake up at least once every night and we have to go in and soothe her back to sleep.I start her bedtime routine (Bath, bottle, bed) usually by 6:30 and she's asleep no later then 7-7:30.till, my husband and I often hear her wake up at least once every night and we have to go in and soothe her back to sleep.
