Ive breastfed all four of my children and this is the advice I wish I'd had at the beginning -
Breastfed babies don't have a 'schedule'. They feed on demand, as much or as little as they like. It could be five times in an hour, or once in three hours. Some days it does feel constant. Ignore anyone who makes comments like ' baby can't possibly be hungry again' etc.
They don't breastfeed just for food. They like to suckle at the breast as it makes them feel really safe and secure, and they love being close to mum. When my children were babies putting them to the breast always calmed them almost instantly. Google the fourth trimester, it explains alot of this.
It can be slightly painful in the early days. I almost gave up, but my mum encouraged me to persevere and I'm really glad I did.
I co slept with my babies, which meant I didn't need to get up through the night, i could just lie and doze while they fed, which was great as I had older children to look after the next day and needed all the rest i could get. They all seemed to sleep really well snuggled in beside me. They all transitioned to their own bed at age 1 really well too. If you follow the guidelines on co sleeping it can really help you get lots of rest during the night.
If you want to introduce a bottle, do it early. With my second and fourth babies I didn't introduce a bottle until after 4 months, and they point blank refused. I couldn't ever get them to take one which was hard as j could never leave them with anyone. It was much easier with my other two babies who could be left with their dad or a family member for an hour here or there whilst I went to the dentist, got my hair cut etc. I introduced a bottle of expressed milk at 4 weeks old.
Dont be afraid to ask for help with other jobs while you are feeding the baby. Also, learning how to put baby in a wrap slimg can be really helpful as they can feed while you go about your business.
Good luck!
