I am just wondering if I could pick your brains for advice on setting a routine for my 5.5 month old son. A bit of background - he was a fantastic sleeper, doing 10 hours overnight from 10 weeks, until we hit just over 4 months. The last 6 weeks have been a blur of stumbling through a sleep regression and just when we wet settling from that and getting 11 uninterrupted hours out of him, he started rolling over in the cot. He is just starting to get the hang of sleeping long stretches again (up to 7-8 hours), but his waking time is erratic to say the least. He may/may not wake through the night, and even if I offer a feed, he doesn't always take much. I should also add that after some training, he settles himself well in the cotton naps and night sleeps.
I have to go back to work in a couple of months and am wondering whether it is worthwhile to start putting a bit of structure into our day, with a consistent sleep/wake time each day. Every time I think he is setting such a thing for himself, he throws a curve ball at me. For the most part, once he is awake, we follow loosely feed, play, sleep (and play if he wakes early) every 3-3.5 hours (depending on if he has had solids).
Other information that might be relevant - he feeds (breast fed) 5 times a day, 3 of those feeds are followed by solids. In a couple of weeks, once he reaches 6 months, I will be weaning the middle 2-3 feeds to formula over the course of a few weeks.
I would love and appreciate your feedback - what worked for you, what didn't? Is it even a good idea to try a routine?
Thanks so much!
