What are you wanting baby’s day to look like at daycare? Solids only? An occasional bottle? Whole milk? Nursing just when you’re actually with baby?
I don’t want to make recommendations, because every baby is different, but our struggle with getting more solids was basically because DS is a boob-man, and refused to eat solids when he knew he could get the “good stuff” if he held out. Unfortunately he stopped growing and was even losing weight, so we had to force the issue. Instead of giving you advice, I’ll just tell you what our ped recommended and what worked for us.
1. Make the most of the little baby will eat. For us, this meant adding butter, olive oil, coconut oil, etc to purees and other things he would eat (DS loves toast, so that was easy. Also pancakes, etc.)
2. Always choose the item with higher fat content (DS loves cheese–make sure it was whole milk cheese).
3. You don’t want to start whole milk until 12 months, but when baby starts daycare, that should be an option. My son doesn’t love it, but he’ll take it on occasion.
4. You may have to give up feeding on demand and establish more of a schedule. For us, it also meant that if he didn’t get enough solids, I DIDN’T nurse him, and instead, offered him more solids (usually something he was more familiar with). My little was also making up for a lot of calories at night, so if you haven’t night weaned yet, you may need to move in that direction.
Like I said, I’m not sure this is the best advice for you, as long as your baby is still growing well, maybe it’s best to work on getting her to accept breastmilk from a cup instead. But it maybe gives you somewhere to start from.
