Ditto IMO.
Please believe us when we say it will settle down. My littlun was just the same, but by 2.5/3 months this had settled down and he was sleeping 8/9 hour stretches at night, just waking up for one or at most two night-feeds.
Everyone has this idea that a bottle-feed in the evening will magically make a baby sleep through - it won't! Sleeping through is as much about the baby learning to cope with being separated from mum at night as it is coping without food. It's a maturity thing and you can't expect a really wee baby to manage it!
If you're not having any probs with breast-feeding other than he's doing it a lot, just stay with it and enjoy it! It's brilliant bonding for you and him, and whilst you're breastfeeding you definitely can't be expected to do anything else like cook so I sincerely hope you're being waited on hand and foot!
It seems like you'll never do anything other than breastfeed at the moment, but it passes really frighteningly quickly. I felt exactly the same, but then all of a sudden there I was with a fully weaned 8 month old who only had 2 breastfeeds per day (first thing in the morning and last thing at night). It's not even a whole year - just a few months in your lifetime is nothing, but if you stick at the breastfeeding for your littlun until he's ready for the solid stuff, you'll have done him and yourself proud and you'll feel totally brilliant about it!
Good luck and remember to come back if you need more support - or find a breastfeeding support group. Your HV should know if there's one near you. They're really good just for a chat and a meet-up as well as getting lots of advice on breastfeeding.
