Ang sleep pattern ng baby talaga ay very gradual ang pagbabago, lalo na sa first few months super unpredictable pa lang sila kasi di pa sila alam ng day and night! Usually around 3-4 months you'll start seeing a bit more consistency, tapos by 6 months mas magiging regular na sila ng sleep-wake cycle, pero honestly it varies talaga per baby, some ng friends ko ang babies nila nag-settle na by 2 months, iba pa rin chaotic pa rin hanggang 8-9 months hehe. The best thing is to just follow their cues muna, establish gentle routines like consistent bedtime, at be patient because their brains are still developing that circadian rhythm. Sobrang frustrating nung newborn stage pero it gets better, I promise!
