Hi there,
I replied on the breastfeeding post where you asked for help. So, I'm just going to add on here.
Babies go through a lot of major changes in their life. There are a few growth spurts along the way and usually a sleep regression at 6 months. Most people expect babies to sleep through the night and a lot of research shows and prove that it's unrealistic expectations that we have. It is in fact, NORMAL for babies to wake up during the night. Be it due to teething, illness, hot/cold, comfort, hunger and also when developmental milestones are going to happen for example, sitting alone, crawling, rolling over, walking etc.
There are also 10 wonder weeks that happen before the age of 2. You can google it for a bit more info.
I know it can be tiring but your lo will sleep through EVENTUALLY. If there is no medical problem like middle ear infection or even reflux, don't stress about it. I don't believe in sleep training. I trust my child and I just make sure that I'm always there. This is just my personal opinion.
You can even google ISISONLINE. Excellent website regarding sleep in children. What is normal and what is usually the normal age for them to start sleeping through, which is usually only after the age of 2 onwards.
We also co-sleep, still bf on demand and my boobies are my son's pacifier which is the original thing
You are not creating bad habits. There is a reason why your lo is waking up. She is also making up for missed boobie time and wants to be close to you. YES, it is exhausting but it will get better.
