Oo normal yan, mommy! At 3 weeks, ang baby mo ay still adjusting sa mundo, kaya ang sleep schedule niya ay everywhere pa, meaning your sleep will be everywhere din haha. A few of us sa mum group namin, parang zombie kami for the first month dahil baby would sleep at random times lang, so we'd sleep whenever we could too. But since you're also not sleeping well even when baby sleeps, I'd gently suggest checking with your OB or pediatrician about it, kasi sometimes new moms develop anxiety or postpartum issues na nakakaaffect ng sleep talaga. Take care of yourself too, mommy, kaya mo yan, but you need rest din!
