Recently my 3 month old (just, he’s 13.5 weeks) usually goes down at 2030, wakes at 0130 and then 0500 for feeds and then again an 0630. This pattern has been interspersed with nights with more frequent wakings at times, although a few weeks ago he was sleeping through til 0230-0330 and then til the morning, around 0730. No properly set pattern - or improvement.
On Tuesday night however, he slept from 2030 through til 0610!! The only difference was the heating was off all night. Last night I kept the heating off again but he was back to his old 0130/0500/0630 routine.
Any ideas on how to improve his sleep, please? He clearly CAN go for nice long stretches, under the right circumstances...
