I found the first 3 months the most challenging and then a routine of sorts developed. I used a hammock to mostly settle my newborn but would also use a HAB sling and a Ergo and I found these wonderful because I wouldn't need to go off into another room to put the baby asleep, leaving my toddler to fend for herself (which was her time to the exact opposite of what I'd asked her to do!)

My toddler was allergic to dairy as a baby and reacted to it through my breastmilk - asking to be referred to a paed or allergist might be a good idea. I restricted my diet as I wanted to continue to breastfed and continued that on for some time. When we weaned at 22 months I reintroduced dairy to my diet.

Do you have any other support around? Have you joined a Mother's group or ABA group or have friends that you can pop over to with the kids during the day.

If you can manage to get their day sleeps to coincide eventually that would be wonderful for you - my toddler decided to drop her sleep though when the new baby arived so it was very rare here!

Hang in there, it DOES get better. It's a tough transition one to two I think!
