You'd think I'd have a clue, she's my 3rd baby, but when the others were little we were in the house all day, and they just fell into a routine naturally. I was never strict about it, but liked to know roughly when naps and bedtime would be, and that they were getting enough sleep.
DD is 3 and a half months, and we have no routine. Naps are random. Some days she'll have an epic 3 hour nap in the morning or middle of the day. Some days she'll have a series of 45 minute naps. Some days she hardly seems to sleep at all, then will crash out around 5pm and sleep until 9ish (then be up until midnight). Overall I don't think that she gets enough sleep.
On a good day, bedtime is 10-11pm. This has been fine up to now, but I start a course next month and will need evenings to study.
At the moment our day (as a family) looks like this:
8am - school run, in car. About half an hour there and back.
12.30 - nursery run on foot. About 20 minutes there and back.
2.30 school run in car. Half an hour, with some hanging about the playground in the middle.
4pm nursery run on foot. 20 mins again.
I usually take DD on the nursery run in a sling, but can also use a pram. She used to sleep well in her car seat (and I could just lift it in to the house / transfer her to a Moses basket) but now it's short naps only in the car seat, and she doesn't transfer well.
Any idea how to build a loose routine, aiming for bed by around 8pm, around this? And how to get there from our current state of randomness? She's a good sleeper at night, and can fall asleep on her own (e.g on her baby gym) when tired (and equally will stay awake in the car if not tired, but almost always sleeps in the sling regardless of when her last nap was). She's exclusively bf, there's not much pattern to when feeds are either
