Depends on where you are with your weaning journey and naps I suppose, and what you mean by cooking dinner - for you, for baby or for both to eat together?
I have 2 kids, now 1 and 3.
My routine has always been dinner altogether, play, story, nappy, bath (if it's bath night), PJs, sleeping bag, another story, breastfeed to sleep, plonk in cot. The time always flexed around hunger or tiredness cues came in.
Bedtime used to be about 630 (so we'd eat about 445/5), and then by 545 we'd be tidying and having story ready for bath about 6 and settling down for sleep by 630. Nowadays, it's about 715 settling down to sleep.
When youngest was tiny we'd have the second story in my bed while baby fed to sleep, toddler tucked under my arm snuggling the other side reading the story. Then we'd dump baby in the cot next to my bed and sneak out with me and toddler so I could tuck toddler in their bed in their room.
Now they're bigger, the second story is in the eldest's bedroom, we say good night and tuck in my eldest and I take the littlest to their bed.
What's your routine at the moment?
