Mommy anxieties

Anyone else going through constant worry and googling? I feel like I google the same things everyday, even though I know the answers “how much should a three month old eat per day” “how much sleep should a three month old have” “what milestones should my 3 month old reach” all to just tell me everything I am doing is right on target. I am a FTM staying at home and My entire day is monopolized by worry and self doubt and googling EVERYTHING. Why do I still feel so anxious and defeated even when I seem to have a well adjusted happy baby ?
