Hi all, I’m new to mumsnet so sorry if this gets asked a lot or if I’m being totally stupid
my baby is 6 weeks old today and so far we haven’t really established any kind of routine with feeding or sleeping. She is formula fed and feeds roughly every 2.5-3 hours in the day and 3-4 hours in the night but she is fed on demand when she is hungry. We take her to bed when we go to bed which isn’t really a set time (sometimes 10pm, sometimes 8pm depending on the day we’ve had) and I get her up in the morning at whatever time she wakes up for feeding. She sleeps during the day after most feeds and has some awake alert time where we play on her play mat or look at toys together.
My question is really should we have more of a set routine for getting up/going to bed and her daytime naps or is she still too young? I think I am questioning myself because I have had a few (older) members of my family ask me what time we feed her and when her nap times are and when I said “whenever she wants” I was looked at like I was completely insane 
Any advice is welcome! Thank you
