I have a 2year old toddler in a very strict routine and it works fantastic for us. I've just had our second Bub who is now 2 weeks old and mostly fed 4hourly since birth and been a fairly good sleeper too. Obviously the week we were in hospital we just went with her demands/having to wake her every 4hours as she often didn't herself and the nurses insisted on it as she was jaundiced.
Anyways we really want them to be in the same routine but we aren't sure if it's too early to be putting the new Bub in such a strict routine. As in having a shower at 6:30pm as we don't have a bath so we need to shower with them and in bed by 7pm after a bottle. The last few days she's woken herself by 6pm so it's been ok but tonight she was still sound asleep. Now I do believe in not waking a sleeping baby but went against my gut and woke her for a bath which she got pretty angry over.
I dunno what to do if we have her in the toddlers nighttime routine she has a feed like 10:30-11 before hubby goes to bed then only wakes once during the night for a feed which is great for us. Not sure how often she would wake if she just went to bed whenever she wants.
Gosh I feel so clueless right now even tho this certainly isn't new territory. :s
