HI Kaa - ok, my DS is 5 months - so this is quite recent for me. My DS now settles after about 5-10 mins max of crying or grumbling without a dummy at 6.30pm - feeds again at 10pm, then sleeps through till about 6.30pm or 7pm, maybe waking in the night on the odd occasion, but I settle him with a dummy. So, the advice I will give you is based on fact it worked for me, but obviously can't guarantee the same for you - but worth a go eh?
bottle at 6am (5ozs)
Presume this is when he's waking, so sounds right to me.
bottle & baby rice at 9.30 (probably 4ozs)
I would put him down for a morning nap earlier - e.g 8 or 8.30am if he's waking at 6am and feed him when he wakes up from this nap. Your feed time would stay the same. If your HV is saying give him solids, and you as his mum feel this is the best thing, then I would move these solids to the lunchtime feed. I'm sure you know the guidelines but you are a grown woman and can make your own decisions IMO as long has you have all the facts.
nap at 10am til 11.30 (he wakes on his own) He would now have this as his awake time.
bottle (5ozs) at 12 - this is when I would give the solids.
usually walk in pram with dogs (or out shopping) for 90mins at 1pm when he'll sleep for about 2hrs.
It might be worth trying to get him to do this sleep in his cot or basket some days to get him used to settling himself to sleep without the rhythm of being pushed. It'll be good practice for night time.
bottle at 3.30 (5ozs)
Give this earlier - nearer 2.30pm if you can.
Try putting him down for 15 mins- 30mins for a nap around 4 ish.
bottle and baby rice at 5pm - he's hungry again
Give him half his feed at 5pm, then the rest after his bath.
bath at 6pm (not every night)
worth making this a nightly ritual, IMO.
bed 7pmish
Maybe try for earlier - I don't take DS downstairs again after bathtime. He gets in his sleepsuit, has the rest of his milk and some solids (which he has just started, as he is 19lbs and is almost off the centile scale at the top end before anyone jumps down my throat!). If you do bathtime at 5.30pm you can usually eek the whole thing out into one longer bedtime routine.
bottle 8pm and 10.30 - Feed him whenever he wakes after settling him at night, lots of babes likes to cluster feed at this age, particularly at this time of night - it's completely normal.
I hope the above is of some help - it just reflects my own experience. If you want, I can tell you in more detail what my DS's daily routine is - I go back to work in a few weeks too, so really had to get him into one before that happened.
