Feeding FAQ: 8-12 weeks – Formula Feeding

My 10-week-old baby has three teeth; his discomfort is making the routine hard

My baby is only 10 weeks old and has three teeth, the fourth is coming through. Teething problems are putting getting onto the routines out the window. We have been trying to follow them for the last 2 weeks. Because of his age there is not anything he is allowed to take to help his discomfort.
He weighs 17lbs and has 6 8oz feeds in the day at 8am, 10am, 1.30pm, 5pm, 8.30pm and 4.30am. Following our health visitors advice he is taking a small bowl of baby rice as well.
He naps from 11am-1pm and 3-3.30pm. He settles at 9.30pm.

As your son has started to teeth so early take him to your doctor and ask for medication to be given to you. At his weight he should be able to take things usually given to older a babies but a doctor needs to supervise the quantities.
To get your son more onto the timings set out in the routines you will need to shift your whole day earlier by starting at 7am. At present he is having a feed at 4.30am and obviously settling until 8am. Begin to wake him 15-20 minutes earlier every few days to get his body adjusted to waking earlier and having a feed. You could try to move him back a whole hour at once but it may put the rest of the days timings out.
Follow the timings laid out in the 8-12 week routine. You will see that this will push on the times he feeds a little. By waking him at 7am you can put a short morning nap into place. His longer sleep of the day should be later, around lunchtime, which will coincide with his natural dip in alertness. He may need a very short nap in the afternoon but should be awake by 5pm. Give him his bath around 5.45pm and follow it with a bottle. Settle him for the evening much earlier than you have been but then wake him for a feed at 10/10.30pm. By moving his feeds in this way he should begin to sleep his longer stretch in the middle of the night, from 11pm onwards and may well get well beyond 4.30am. If he wakes before 7am having slept all through try to settle him with a small feed until 7am or if it is around 5/5.30am give him a feed and settle him back to sleep. At 7/7.30am wake him and offer him a smaller feed so he is able to get back to being fed again at 10.45am.
