Hi there.
I wonder if you have managed to sort out the sleep issues with your baby, but just in case, here is my two cents worth.
Can you give me some indication of when you are feeding your baby solids during the day? It may be that you are giving your baby too many solids so that he isn't hungry enough to drink his milk during the day. Milk should come first and foremost until the age of 12 months, after which you can reduce the amount of milk and increase solids.
Ideally, your baby should be waking up and having his first bottle at about 6am, then following with breakfast at about 7.30am. You need at least an hour to an hour and a half between feeding solids and milk, or he won't be hungry enough.
Breakfast should be light with fruit, yogurt, possibly some porridge.
He should then be hungry enough to have another bottle at about 10.30am and lunch should follow at about 12.
Again, milk before he has an afternoon sleep (also helps to calm him), and then an early dinner between 4 and 5pm.
He should have another bottle before going down to sleep and you need to leave enough of a gap before this bottle to ensure that he is still hungry so that he drinks the whole bottle. Have you thought about changing the teat? If you are still using a 3-6 month teat, he may be getting frustrated with how hard he has to work to get the milk out of it. Put him on a 12m+ teat so that he doesn't have to work as hard to get to his milk.
If he has had this kind of intake during the day, he shouldn't need to wake up again for at least 7 hours. You may find that if he is going through a teething period, or if he going through a growth spurt, he may want more milk at about 2am, but really he should be able to go through the night. Try increasing the amount of protein in his dinner food, which will keep him fuller for longer.
Another thing to consider is the use of a sleeping bag for your baby. It may be that he is waking up at night out of a loss of a sense of security, having kicked his blankets off. Try using a 100% cotton sleeveless sleeping bag (see
www.dizzydots.co.za or
www.babysense.com), as this increases your baby's sense of securitty and will help him settle better and quicker at night on his own when he does wake up, without him having to need you.
I hope that some of this will help, but please feel free to ask any questions you might need to. My gut feeling is that you need to reduce the amount of solids you are giving him and ensure longer periods between milk and food. If this is something you have already tried, or are doing and isn't working, then I suggest you speak to someone at your local pharmacy where there may be a baby clinic or sister who can help check out other potential problems, such as allergies to milk etc.
